User story: As an administrator, I want to define which user groups Automoderator should never revert edits from, so that I can constrain its actions to certain kinds of users.

We want to give communities the ability to target Automoderator however they want to, while also reducing false positive rates. Although Automoderator will effectively never revert an administrator or user with other advanced user rights, it's possible that it may revert users with just a few user groups, even if those groups imply a level of community trust. Additionally, communities may wish to only target Automoderator on users who aren't logged in to an account, or have not passed some activity threshold.

A new MediaWiki and wiki config for user groups to skip should be added. When checking to see if we should revert an edit, if the targeted user has one of these user groups, they should not be reverted.
