doc/rados: explain replaceable parts of command
Add an explanation that directs the reader to replace the "X" part of
the command "ceph tell mon.X mon_status" with the value specific to the
reader's Ceph cluster (which is (probably) not "X").
In the future, such replaceable strings in commands may be bounded by
angle brackets ("<" and ">").
