cli: add geo-replication log-rotate command
Rotating geo-replication master/monitor log files from cli.
On invocation, the log file for a given master-slave session
is backed up with the current timestamp suffixed to the file
name and signal is sent to gsyncd to start logging to a new
log file.
Sample commands:
* Rotate log file for this <master>:<slave> session:
gluster volume geo-replication <master> <slave> log-rotate
* Rotate log files for all session for master volume <master>
gluster volume geo-replication <master> log-rotate
* Rotate log files for all sessions:
gluster volume geo-replication log-rotate
