[FEATURE] Add support for locally cached modules

[masonbivens]

There should be a mechanism that allows you to leverage modules that have been downloaded already via the terraform init process. This could potentially offer an easy workaround for the different scm platform integrations, until they are fully fleshed out within the application as well.

Good idea. Right now FYI the modules are cached in the hidden folder ~/.terravision and they don't get downloaded the second time if you refer to the same module next time.

@masonbivens I have updated the code to allow all the SCM integrations that Terraform supports. Please check if this is still necessary ?

So this is the error I'm getting now, it seems like it can't leverage private terraform modules from Gitlab. It may be helpful to be able to leverage a users .terraformrc file for handling the credentials for terraform module registries.

@masonbivens Have you tried the latest code? Can I close this issue?
