Changes include:

- Ensure Member.add_user is not called directly when not necessary
- New GroupMember.add_users_to_group to have the same abstraction level as for Project
- Refactor Member.add_user to take a source instead of an array of members
- Fix Rubocop offenses
- Always use Project#add_user instead of project.team.add_user
- Factorize users addition as members in Member.add_users_to_source
- Make access_level a keyword argument in GroupMember.add_users_to_group and ProjectMember.add_users_to_projects
- Destroy any requester before adding them as a member
- Improve the way we handle access requesters in Member.add_user
  Instead of removing the requester and creating a new member,
  we now simply accepts their access request. This way, they will
  receive a "access request granted" email.
- Fix error that was previously silently ignored
- Stop raising when access level is invalid in Member, let Rails validation do their work

Send ajax request for label update only if they are changed

## What does this MR do?

At the moment we send requests to update the labels on issue even if nothing has been changed. This fixes that and only sends requests when something has actually been changed.

The code gets the initial selected values based on the inputs & then compares that to the selected values when submitting. If they are equal, then no request is sent.

## What are the relevant issue numbers?

Closes #19472 

See merge request !5071

Fix pipelines table headers

## What does this MR do?

## Are there points in the code the reviewer needs to double check?

## Why was this MR needed?

The headers were messing the table up. Note the redundant headers and squished cells.

* No need to re-fetch issues from GH to read their labels, the labels
  are already there from the index request.
* No need to look up labels on the database for every application, so we
  cache them.

This should avoid having large memory growth when importing GitHub repos
with lots of resources.
