Martin Atkins ffe056bacb Move command/ to internal/command/
This is part of a general effort to move all of Terraform's non-library
package surface under internal in order to reinforce that these are for
internal use within Terraform only.

If you were previously importing packages under this prefix into an
external codebase, you could pin to an earlier release tag as an interim
solution until you've make a plan to achieve the same functionality some
other way.

// TestProviderDevOverrides is a test for the special dev_overrides setting

// developers to opt out of the version number and checksum verification
// we normally do, so they can just overwrite the same local executable
// in-place to iterate faster.

// to actually run it. For now we'll use the "test" provider for that,
// because it happens to be in this repository and therefore allows
// us to avoid drawing in anything external, but we might revisit this
// strategy in future if other needs cause us to evolve the test
// provider in a way that makes it less suitable for this particular test,
// such as if it stops being buildable into an independent executable.
