Background

We have acoder_external_auth data source that requires the user auth with git or another sevice before creating the template.

Current behavior

When git auth is added to a template, it is currently required. However, some organizations are migrating from one git provider to another or rolling out a provider to others. This means not all template users have an account on a given service. Terraform is also capable of conditional logic, such as cloning a repo if the user authed

Proposed behavior

A provider can be marked as optional.
