user's permissions on Issues/PRs

[marusinm]

Updated by @lachmanfrantisek :

We have a lot of methods related to the permissions (e.g. who can merge/close,..)

It's not consistent, let's clean that!

Feel free to solve this in smaller parts. Just write on what you are going to work...

AC:

• Make sure, that we have all of the provided methods in the abstract.py
  (raising the NotImplementedError)
• Make sure, that we have all of these in all the implementations:
  • GitLab
  • GitHub
  • Pagure
• Deprecate the project methods related to specific issue/pull-request.
• Move helping methods to the base classes.
  • The only exception is a more efficient solution in the code of the specific implementation.
  • Example:
    https://github.com/packit-service/ogr/blob/89435655150b8dd79ef93209c3463585d0715e0d/ogr/services/github/project.py#L219-L220

The progress is tracked in the following tables. (Any update in the comments is appreciated.)

Project	who_can_close_issue() -> Set[str]	who_can_merge_pr() -> Set[str]	can_close_issue(username: str) -> bool	can_merge_pr(username: str) -> bool

base	nothing	nothing	implement here	implement here
Github	?	?	?	?

I've updated the description. This issue is now about cleaning the methods and add the missing parts. Please, check if I don't forget anything.
