glusterd/geo-rep: Handle empty monitor.status during upgrade
Problem:
Consider geo-replication is in Stopped state.
Following which, glusterfs is upgraded (where monitor.status is the new status file).
Now, When geo-replication status command is run,
empty monitor status file gets created.
Now, if glusterd is restarted, it reads empty monitor status
and starts geo-replication session. This is incorrect as session
was in Stopped state earlier.
Solution:
If monitor status is empty, error out and avoid
starting geo-replication session.
Note: if monitor status is empty, geo-rep session is displayed
as Stopped state.
