Add some documentation for MONs being looked up using DNS by librados.

As per http://tracker.ceph.com/issues/14527 / #7741

_ceph-mon._tcp.example.com. 60 IN SRV 10 60 6789 mon2.example.com.
_ceph-mon._tcp.example.com. 60 IN SRV 10 60 6789 mon3.example.com.

In this case the Monitors are running on port *6789*.

@wido could you please amend this part with something like:

In the example above, all monitors are configured with priority of 60 and weight of 10. But please note, the priority and weight are not respected yet. So all monitors resolved using DNS are considered equal, and Ceph client will pick a random one from them when connecting to the cluster without taking these settings into consideration.
