Provide a custom rubocop plugin

[bastelfreak]

Use Case

There are some requirements to the ruby code in types/providers/functions/facts. For example using require_relative and not require. I think it would be great if Perforce could provide a rubocop plugin for all of us. I found
https://github.com/big-samantha/rubocop-facter but that's quite old and only provides two cops. But it's a good start.

Describe the Solution You Would Like

Provide a way for developers to detect code smells in types/providers/functions/facts via static code analysis.

Describe Alternatives You've Considered

Additional Context

I'm not 100% sure if this is the right place for the issue. Please let me know if I should move it.
