Description

This is a subtask as a result of discussions around design in OAK-4796:

Based on the ChangeSet provided with OAK-4907 in the CommitContext, the ChangeProcessor should do a best-effort prefiltering of commits before they get added to the (BackgroundObserver's) queue.

This consists of the following parts:

• the support for optionally excluding commits from being added to the queue in the BackgroundObserver EDIT: factored that out into OAK-4916
• the BackgroundObserver signaling downstream Observers that a change should be excluded via a NOOP_CHANGE CommitInfo EDIT: factored that out into OAK-4916
• the ChangeProcessor using OAK-4907's ChangeSet of the CommitContext for best-effort prefiltering - and handling the NOOP_CHANGED CommitInfo introduced in OAK-4916
