Description

when a mon node joins the cluster, it should check to see if it is on a compatible version (within family) and fail if it is not, unless --yes-i-am-really-really-sure is specified. this helps eliminate split brain scenarios when adding mons. Ceph-deploy could utilize the same check if it is built into ceph mon add.
