Add -no-color option for terrafrom workspace

[jlpedrosa]

Current Terraform Version

Terraform v0.11.10

Use-cases

We have a system that can create N environments through terraform. We are using workspaces for the N environments. It's an automatic system so we are running commands, and parsing the output, with colors sometimes is more inconvenient.

Proposal

add -no-color option for all the commands available

workaround: TF_CLI_ARGS="-no-color" works for workspace even if it undocumented

[transfr-kennedy]

Is there a way to revive this/formalize it? It'd be great if -no-color was a global option.
