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 Change-Id: If801743e9f37bd282e68d262203141626ce77e55 BUG: 3519 Reviewed-on: http://review.gluster.com/653 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Csaba Henk <csaba@gluster.com>
