Make possible *.auto.tfvars in workspaces

[voroniys]

Current Terraform Version

Terraform v0.11.11

Use-cases

When I create a workspace it is vary usefull to also have a possibility to load workspace related tfvars files, so it would be not needed to provide -var-file option

Attempted Solutions

At the moment -var-file needed each time, what is inconvinient and possibility for errors (choose wrong file).

Proposal

When workspace created create terraform.tfvars.d/<ws_name> directory in addition to terraform.tfstate.d/...
Than for terraform plan/apply look for *.auto.tfvars files also in this new terraform.tfvars.d/<ws_name> directory.
This is really "low hanging fruit" - it can be done quite easily, but will drastically improve usability of terraform workspaces.

I also use the pattern of "linking" tfvars to workspaces.

In order to minimize the risk of errors, I always use the same command line: terraform apply -var-file="environment-variables/$(terraform workspace show).tfvars".

Then, $(terraform workspace show) expands to the currently selected workspace so when, say, on workspace "development" it will use environment-variables/development.tfvars but when workspace "production" is selected, the same command line will use environment-variables/production.tfvars instead.

But there's another interesting thing in your request: the tfvars.d/ part, since I'd find great if the var-file option (or something related), allowed for a full directory of *.tfvars files instead of a single one. In fact, I found about this while reviewing issues in case someone already requested it, prior to open a feature request myself.

I just opened #27569 requesting the ability to load a directory of *.tfvars files instead of just one.
