Module version

Changes

Allow the caller of the module to upgrade/downgrade version of the provider without needing a new release of the module.

Sorry, missed this PR -- can I ask what the motivation for it is? And have you checked if the changes here are backwards-compatible or not?

[hbjydev]

I think part of me would rather just bump the provider version in the module so it remains explicit, because we're using implicit versions as part of some of our automation at ALT-F4.

This would allow anyone who wants to reutilize this module to set the provider version for github at the top level, right now being a hardcoded fixed version deep in the module logic, it's very limited and always would require a new release of the module.
Thus the module defining a version constraint, or version interval that it supports, you can specify explicitly the version for the
given provider at the top level of the project.
