Description

Remove `org.apache.james.mailbox.acl.GroupMembershipResolver` , `SimpleGroupMembershipResolver` and related implement.

Reason:

• Interface GroupMembershipResolver has only one implement is SimpleGroupMembershipResolver. As the author's comment: "There is no persistence. You will get only what you add".

And nowhere in James call to `.addMemberShip` method => `.isMember` always return FALSE.

Remove the exuberancy code to make it simpler.
