Subject: [PATCH] Add hint about -c/--fast-checkpoint

When cloning a server without this option, and pg_start_backup() takes time
to complete, repmgr appears to hang and give no indication of what may
or may not be happening. The hint provides an explanation for any
delay and possible action which could be taken to mitigate it.
