New Feature Request: Support TFE TF Cloud tokens

[dmedeiros204]

Describe the feature To access remote backends and a tfe module registry you must provide credentials. If we could populate this token as an option it would mean not having to create a secured file

credentials "app.terraform.io" { token = "xxxxxx.atlasv1.zzzzzzzzzzzzz" }
