Set domain source action

There is sample code in Drupal\domain_access\Plugin\Action that could be used to create these. I'm open to it.

Added two types of actions: one for unset domain source and one for setting the domain source per domain.

I have tested it out and if the content is assigned to all affiliates it is not working. I also added extra update access check.

Attaching proper file as there are new files added/

Looks pretty good on first review.

It should really have a test. There is a similar one in domain/tests/src/Functional/DomainActionsTest.php

After testing, I'm not seeing the "Set" action for existing domains. These should be handled in the install function also and not only in the update function?

Also a small PHPCS issue with a t() that should be a $this-t() and another small PHPCS issue.

The tests are not that easy to add, so leaving that open and adding the issue tag.
Setting this to NR for the changes, can be set back to NW afterwards for the tests.

The patch is working for me. After running updates and clearing the cache, I can set the source origin. The only thing is that the domain must have already been checked in Domain Access, which is correct.

Could we have a MR on 2.0.x please ?

Simple test added. Looks like we are ready for merge.
