The Ceph CLI has the flag option '--connect-timeout' which controls the
timeout of the command when reaching out to a monitor. If the connection
cannot be established within 15 seconds, the command will fail. The
default value in Ceph is relatively long (300sec IIRC). This is a
problem when monitors have trouble reaching out quorum, since this means
the command will only fail after 300 sec.
Now we fail faster.
