James Bardin 4f5e92e4c0 reverse init test to check for dataDir in PWD
init should always write intternal data to the current directory, even
when a path is provided. The inherited behavior no longer applies to the
new use of init.

Martin Atkins 6979a07754 command: init -upgrade for provider plugins
Now when -upgrade is provided to "terraform init" (and plugin installation
isn't disabled) it will:

- ignore the contents of the auto-install plugin directory when deciding
  what is "available", thus causing anything there to be reinstalled,
  possibly at a newer version.
- if installation completes successfully, purge from the auto-install
  plugin directory any plugin-looking files that aren't in the set of
  chosen plugins.

As before, plugins outside of the auto-install directory are able to
take precedence over the auto-install ones, and these will never be
upgraded nor purged.

The thinking here is that the auto-install directory is an implementation
detail directly managed by Terraform, and so it's Terraform's
responsibility to automatically keep it clean as plugins are upgraded.

We don't yet have the -plugin-dir option implemented, but once it is it
should circumvent all of this behavior and just expect providers to be
already available in the given directory, meaning that nothing will be
auto-installed, -upgraded or -purged.

Martin Atkins f753974bb3 plugin/discovery: Installer interface, and provider implementation
Previously we had a "getProvider" function type used to implement plugin
fetching. Here we replace that with an interface type, initially with
just a "Get" function.

For now this just simplifies the interface by allowing the target
directory and protocol version to be members of the struct rather than
passed as arguments.

A later change will extend this interface to also include a method to
purge unused plugins, so that upgrading frequently doesn't leave behind
a trail of unused executable files.

Gavin Williams 5834333ea3 command: terraform get -upgrade
As of this commit this just upgrades modules, but this option will also
later upgrade plugins and indeed anything else that's being downloaded and
installed as part of the init.

James Bardin 2bfcdbbd08 change init args to remove source copy
When init was modified in 0.9 to initialize a terraform working
directory, the legacy behavior was kept to copy or fetch module sources.
This left the init command without the ability that the plan and apply
commands have to target a specific directory for the operation.

This commit removes the legacy behavior altogether, and allows init to
target a directory for initialization, bringing it into parity with plan
and apply. If one want to copy a module to the target or current
directory, that will have to be done manually before calling init. We
can later reintroduce fetching modules with init without breaking this
new behavior, by adding the source as an optional second argument.

The unit tests testing the copying of sources with init have been
removed, as well as some out of date (and commented out) init tests
regarding remote states.

James Bardin d1c50efb01 change providers.json to lock.json
It might not just be for providers, and it's in the plugins dir, so
lock.json seems descriptive enough.

James Bardin fdbfc17fae missing constraints passed erroniously
ConstrainVersions was documented as returning nil, but it was instead
returning an empty set. Use the Count() method to check for nil or
empty. Add test to verify failed constraints will show up as missing.

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.

James Bardin 2994c6ac5d add init getPlugin test
add a mock plugin getter, and test that we can fetch requested version
of the plugins.

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.

James Bardin c891ab50b7 detect when backend.Hash needs update
It's possible to not change the backend config, but require updating the
stored backend state by moving init options from the config file to the
`-backend-config` flag. If the config is the same, but the hash doesn't
match, update the stored state.

James Bardin ff2d753062 add Rehash to terraform.BackendState
This method mirrors that of config.Backend, so we can compare the
configration of a backend read from a config vs that of a backend read
from a state. This will prevent init from reinitializing when using
`-backend-config` options that match the existing state.

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: recompute config hash with ConfigFile set
Fixes #12749

If we merge in an extra partial config we need to recompute the hash to
compare with the old value to detect that change.

This hash needs to NOT be stored and just used as a temporary. We want
to keep the original hash in the state so that we don't detect a change
from the config (since the config will always be partial).

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.
