This was a vestige from earlier prototyping when we were considering
supporting adding credentials to existing .tfrc native syntax files.
However, that proved impractical because the CLI config format is still
HCL 1.0 and that can't reliably perform programmatic surgical updates,
so we'll remove this option for now. We might add it back in later if it
becomes more practical to support it.
These run against a stub OAuth server implementation, verifying that we
are able to run an end-to-end login transaction for both the authorization
code and the password grant types.
This includes adding support for authorization code grants to our stub
OAuth server implementation; it previously supported only the password
grant type.
For unit testing in particular we can't launch a real browser for testing,
so this indirection is primarily to allow us to substitute a mock when
testing a command that can launch a browser.
This includes a simple mock implementation that expects to interact with
a running web server directly.
Because we're going to pass the credentials we obtain on to some
credentials store (either a credentials helper or a local file on disk)
we ought to disclose that first and give the user a chance to cancel out
and set up a different credentials storage mechanism first if desired.
This also includes the very beginnings of support for the owner password
grant type when running against app.terraform.io. This will be used only
temporarily at initial release to allow a faster initial release without
blocking on implementation of a full OAuth flow in Terraform Cloud.
