Martin Atkins 22a2580e93 main: Use the new cliconfig package credentials source
This should not cause any change in behavior yet, but using this new
implementation will allow the "terraform login" and "terraform logout"
commands to store and forget credentials when they are implemented in
subsequent commits.

Martin Atkins e1590d0a70 command/cliconfig: Factor out CLI config handling
This is just a wholesale move of the CLI configuration types and functions
from the main package into its own package, leaving behind some type
aliases and wrappers for now to keep existing callers working.

This commit alone doesn't really achieve anything, but in future commits
we'll expand the functionality in this package.

Sander van Harmelen 52a1b22f7a Implement the remote enhanced backend
This is a refactored version of the `remote` backend that was initially added to Terraform v0.11.8 which should now be compatible with v0.12.0.

Martin Atkins a3403f2766 terraform: Ugly huge change to weave in new State and Plan types
Due to how often the state and plan types are referenced throughout
Terraform, there isn't a great way to switch them out gradually. As a
consequence, this huge commit gets us from the old world to a _compilable_
new world, but still has a large number of known test failures due to
key functionality being stubbed out.

The stubs here are for anything that interacts with providers, since we
now need to do the follow-up work to similarly replace the old
terraform.ResourceProvider interface with its replacement in the new
"providers" package. That work, along with work to fix the remaining
failing tests, will follow in subsequent commits.

The aim here was to replace all references to terraform.State and its
downstream types with states.State, terraform.Plan with plans.Plan,
state.State with statemgr.State, and switch to the new implementations of
the state and plan file formats. However, due to the number of times those
types are used, this also ended up affecting numerous other parts of core
such as terraform.Hook, the backend.Backend interface, and most of the CLI
commands.

Just as with 5861dbf3fc49b19587a31816eb06f511ab861bb4 before, I apologize
in advance to the person who inevitably just found this huge commit while
spelunking through the commit history.

Martin Atkins bd10b84a8e command/format: include source snippets in diagnostics
If we get a diagnostic message that references a source range, and if the
source code for the referenced file is available, we'll show a snippet of
the source code with the source range highlighted.

At the moment we have no cache of source code, so in practice this
codepath can never be visited. Callers to format.Diagnostic will be
gradually updated in subsequent commits.

Sander van Harmelen 179b32d426 Add a `CredentialsForHost` method to disco.Disco
By adding this method you now only have to pass a `*disco.Disco` object around in order to do discovery and use any configured credentials for the discovered hosts.

Of course you can also still pass around both a `*disco.Disco` and a `auth.CredentialsSource` object if there is a need or a reason for that!

Martin Atkins 275ab4a74e main: don't print the CLI config into the logs
Now that we're expecting "credentials" blocks in the config (with auth
tokens for private module registries, etc) we should not print out the
config contents into the log, or else people will probably end up
accidentally disclosing their credentials when sharing debug output with
us, or will be reluctant to share debug output.

Martin Atkins 11ba1d2a4c main: factor out CLI config loading into its own function
Previously we handled all of the config sources directly within the main
function. We're going to make CLI config loading more complex shortly, so
having this encapsulated in its own function will avoid creating even more
clutter inside the main function.

Along the way here we also switch from using native Go "error" to using
tfdiags.Diagnostics, so that we can potentially issue warnings here too
in future, and so that we can return multiple errors.

Martin Atkins a2c59c6ecd main: validate credentials blocks in CLI config
We require that each "credentials" block has a valid hostname and that
there be no more than one "credentials_helper" block.

There are some more sophisticated validations we could do here, such as
checking if the same host is declared more than once, but since this
config handling will be rewritten to use HCL2 in the near future, and this
sort of check is easier to do in the HCL2 API, we just check the basic
stuff for now and plan to revisit later.

Martin Atkins cb17a9a607 main: allow enabling plugin caching via config file or environment
Either the environment variable TF_PLUGIN_CACHE_DIR or a setting in the
CLI config file (~/.terraformrc on Unix) allow opting in to the plugin
caching behavior.

This is opt-in because for new users we don't want to pollute their system
with extra directories they don't know about. By opting in to caching, the
user is assuming the responsibility to occasionally prune the cache over
time as older plugins become stale and unused.

Martin Atkins 3f401f0cd4 main: make configuration available when initializing commands
This, in principle, allows us to make use of configuration information

of that until a subsequent commit.

Martin Atkins 9b5ae9143a main: enable basic subcommand autocomplete
The CLI package has automatic support for shell autocomplete (bash and
zsh, at time of writing) for subcommands, so all we need to do here is
just opt into it.

Users can install this into their shells by running:
    terraform -install-autocomplete

Martin Atkins 8364383c35 Push plugin discovery down into command package
Previously we did plugin discovery in the main package, but as we move
towards versioned plugins we need more information available in order to
resolve plugins, so we move this responsibility into the command package
itself.

For the moment this is just preserving the existing behavior as long as
there are only internal and unversioned plugins present. This is the
final state for provisioners in 0.10, since we don't want to support
versioned provisioners yet. For providers this is just a checkpoint along
the way, since further work is required to apply version constraints from
configuration and support additional plugin search directories.

The automatic plugin discovery behavior is not desirable for tests because
we want to mock the plugins there, so we add a new backdoor for the tests
to use to skip the plugin discovery and just provide their own mock
implementations. Most of this diff is thus noisy rework of the tests to
use this new mechanism.

Martin Atkins 5ac311e2a9 main: synchronize writes to VT100-faker on Windows
We use a third-party library "colorable" to translate VT100 color
sequences into Windows console attribute-setting calls when Terraform is
running on Windows.

colorable is not concurrency-safe for multiple writes to the same console,
because it writes to the console one character at a time and so two
concurrent writers get their characters interleaved, creating unreadable
garble.

Here we wrap around it a synchronization mechanism to ensure that there
can be only one Write call outstanding across both stderr and stdout,
mimicking the usual behavior we expect (when stderr/stdout are a normal
file handle) of each Write being completed atomically.

James Bardin 797a1b339d DebugInfo and DebugGraph
Implement debugInfo and the DebugGraph

DebugInfo will be a global variable through which graph debug
information can we written to a compressed archive. The DebugInfo
methods are all safe for concurrent use, and noop with a nil receiver.
The API outside of the terraform package will be to call SetDebugInfo
to create the archive, and CloseDebugInfo() to properly close the file.
Each write to the archive will be flushed and sync'ed individually, so
in the event of a crash or a missing call to Close, the archive can
still be recovered.

The DebugGraph is a representation of a terraform Graph to be written to
the debug archive, currently in dot format. The DebugGraph also contains
an internal buffer with Printf and Write methods to add to this buffer.
The buffer will be written to an accompanying file in the debug archive
along with the graph.

This also adds a GraphNodeDebugger interface. Any node implementing
`NodeDebug() string` can output information to annotate the debug graph
node, and add the data to the log. This interface may change or be
removed to provide richer options for debugging graph nodes.

The new graph builders all delegate the build to the BasicGraphBuilder.
Having a Name field lets us differentiate the actual builder
implementation in the debug graphs.

James Bardin 6b7a079bff Add a way to avoid panicwrap when debugging
When trying to use a debugger, you don't want the terraform to run in a
new child process. Setting TF_FORK=0 will skip panicwrap and continue
running the program in the current process. This will also give direct
access to log output, and stdout.

Mitchell Hashimoto d1b46e99bd Add `terraform state list` command
This introduces the terraform state list command to list the resources
within a state. This is the first of many state management commands to
come into 0.7.

This is the first command of many to come that is considered a
"plumbing" command within Terraform (see "plumbing vs porcelain":
http://git.661346.n2.nabble.com/what-are-plumbing-and-porcelain-td2190639.html).
As such, this PR also introduces a bunch of groundwork to support
plumbing commands.

The main changes:

- Main command output is changed to split "common" and "uncommon"
  commands.

- mitchellh/cli is updated to support nested subcommands, since
  terraform state list is a nested subcommand.

- terraform.StateFilter is introduced as a way in core to filter/search
  the state files. This is very basic currently but I expect to make it
  more advanced as time goes on.

- terraform state list command is introduced to list resources in a
  state. This can take a series of arguments to filter this down.

Known issues, or things that aren't done in this PR on purpose:

- Unit tests for terraform state list are on the way. Unit tests for the
  core changes are all there.

Paul Hinze 4bd4e18def core: use same logging setup for acctests
We weren't doing any log setup for acceptance tests, which made it
difficult to wrangle log output in CI.

This moves the log setup functions we use in `main` over into a helper
package so we can use them for acceptance tests as well.

This means that acceptance tests will by default be a _lot_ quieter,
only printing out actual test output. Setting `TF_LOG=trace` will
restore the full prior noise level.

Only minor behavior change is to make `ioutil.Discard` the default
return value rather than a `nil` that needs to be checked for.
