Oath has developed an internal patch for our 7.1.x fork which removes cluster
support. This is effectively a back port of changes that are already on master.
The question is whether it would be OK to submit as a backport to 7.1.3. It's
fairly large but it should make backporting from master to 7.1.x easier. I
chatted with Leif as the RM for 7.1.x and he had no objection but wanted to
leave it up to the community. I'm +1 on this. As far as I know, clustering is
already official disabled for 7.1.x and so this doesn't represent a
functionality or API change.
