Martin Atkins 3c429b3628 command init: show log output for each provider plugin downloaded
Each provider plugin will take at least a few seconds to download, so
providing feedback about each one should make users feel less like
Terraform has hung.

Ideally we'd show ongoing progress during the download, but that's not
possible without re-working go-getter, so we'll accept this as an interim
solution for now.

Martin Atkins 4ba20f9c1c command init: show suggested constraints for unconstrained providers
When running "terraform init" with providers that are unconstrained, we
will now produce information to help the user update configuration to
constrain for the particular providers that were chosen, to prevent
inadvertently drifting onto a newer major release that might contain
breaking changes.

A ~> constraint is used here because pinning to a single specific version
is expected to create dependency hell when using child modules. By using
this constraint mode, which allows minor version upgrades, we avoid the
need for users to constantly adjust version constraints across many
modules, but make major version upgrades still be opt-in.

Any constraint at all in the configuration will prevent the display of
these suggestions, so users are free to use stronger or weaker constraints
if desired, ignoring the recommendation.

Martin Atkins 032f71f1ff command: produce provider lock file during "terraform init"
Once we've installed the necessary plugins, we'll do one more walk of
the available plugins and record the SHA256 hashes of all of the plugins
we select in the provider lock file.

The file we write here gets read when we're building ContextOpts to
initialize the main terraform context, so any command that works with
the context will then fail if any of the provider binaries change.

Martin Atkins e3401947a6 plugin/discovery: PluginRequirements can specify SHA256 digests
As well as constraining plugins by version number, we also want to be
able to pin plugins to use specific executables so that we can detect
drift in available plugins between commands.

This commit allows such requirements to be specified, but doesn't yet
specify any such requirements, nor validate them.

James Bardin 2749946f5c basic plugin getter
Add discovery.GetProviders to fetch plugins from the relases site.

This is an early version, with no tests, that only (probably) fetches
plugins from the default location. The URLs are still subject to change,
and since there are no plugin releases, it doesn't work at all yet.

James Bardin 718ede0636 have Meta.Backend use a Config rather than loading
Instead of providing the a path in BackendOpts, provide a loaded
*config.Config instead. This reduces the number of places where
configuration is loaded.

James Bardin 7aa2ce8341 add -reconfigure option for init
The reconfigure flag will force init to ignore any saved backend state.
This is useful when a user does not want any backend migration to
happen, or if the saved configuration can't be loaded at all for some
reason.

James Bardin fb4a365d12 noop migrate copy, add -lock and -input
A couple commits got rebased together here, and it's easier to enumerate
them in a single commit.

Skip copying of states during migration if they are the same state. This
can happen when trying to reconfigure a backend's options, or if the
state was manually transferred. This can fail unexpectedly with locking
enabled.

Honor the `-input` flag for all confirmations (the new test hit some
more). Also unify where we reference the Meta.forceInitCopy and transfer
the value to the existing backendMigrateOpts.force field.

James Bardin 5eca913b14 add cli flags for -lock-timeout
Add the -lock-timeout flag to the appropriate commands.
Add the -lock flag to `init` and `import` which were missing it.
Set both stateLock and stateLockTimeout in Meta.flagsSet, and remove the
extra references for clarity.

James Bardin 54e536cfe0 add `-force-copy` option to init command
The `-force-copy` option will suppress confirmation for copying state
data.

Modify some tests to use the option, making sure to leave coverage of
the Input code path.

command/init: backend-config accepts key=value pairs
This augments backend-config to also accept key=value pairs.
This should make Terraform easier to script rather than having to
generate a JSON file.

You must still specify the backend type as a minimal amount in
configurations, example:

```
terraform { backend "consul" {} }
```

This is required because Terraform needs to be able to detect the
_absense_ of that value for unsetting, if that is necessary at some
point.

command/init: initialize backend even if not set in the config
We need to initialize the backend even if the config has no backend set.
This allows `init` to work when unsetting a previously set backend.
Without this, there was no way to unset a backend.

James Nugent 681d94ae20 core: Allow lists and maps as variable overrides
Terraform 0.7 introduces lists and maps as first-class values for
variables, in addition to string values which were previously available.
However, there was previously no way to override the default value of a
list or map, and the functionality for overriding specific map keys was
broken.

Using the environment variable method for setting variable values, there
was previously no way to give a variable a value of a list or map. These
now support HCL for individual values - specifying:

    TF_VAR_test='["Hello", "World"]'

will set the variable `test` to a two-element list containing "Hello"
and "World". Specifying

    TF_VAR_test_map='{"Hello = "World", "Foo" = "bar"}'

will set the variable `test_map` to a two-element map with keys "Hello"
and "Foo", and values "World" and "bar" respectively.

The same logic is applied to `-var` flags, and the file parsed by
`-var-files` ("autoVariables").

Note that care must be taken to not run into shell expansion for `-var-`
flags and environment variables.

We also merge map keys where appropriate. The override syntax has
changed (to be noted in CHANGELOG as a breaking change), so several
tests needed their syntax updating from the old `amis.us-east-1 =
"newValue"` style to `amis = "{ "us-east-1" = "newValue"}"` style as
defined in TF-002.

In order to continue supporting the `-var "foo=bar"` type of variable
flag (which is not valid HCL), a special case error is checked after HCL
parsing fails, and the old code path runs instead.
