Description
When we added our new osdmap encoding, we changed the on-disk encoding of the map. If old monitors join up, they won't be able to understand the data they receive in transactions!
Prevent them from joining the quorum, and be nice about it.

Going to have to do some manual testing; not sure if there's any feasible automated testing we can set up or should perform on this. :/

Nifty, thanks Tamil! That should let me cover a bunch of it.

- Status changed from In Progress to Resolved
This is merged (and so are some fixes around it), just didn't get the automated tests debugged but they can go elsewhere.
