Blaine Gardner feff587992 ceph: mon service forwards default bind port 6789
The Ceph mon flag `--public-bind-addr` does not keep the same port as
the previous daemon run when the port is left off the flag's value. A
port is undesired since that could interfere with Nautilus' msgr2
protocol, so instead configure the mon's services to forward the default
bind port on pods (6789) to the mon endpoint's port. The endpoint port
will be 6789 for new mons, but it may be 6790 for legacy clusters.
