georep: add reset-sync-time option for session delete
Set the stime xattr at all the brick roots to (0,0) if the argument
reset-sync-time has been provided on the command-line.
To avoid testing against directory specific stime, the remote
stime is assumed to be minus_infinity, if the root directory
stime is set to (0,0), before the directory scan begins.
This triggers a full volume resync to slave in the case of a
geo-rep session recreation with the same master-slave volume
pair.
Command synopsis:
gluster volume geo-replication <MASTERVOL> <SLAVE>::<SLAVEVOL> delete \
[reset-sync-time]
Update gluster cli man page to include new sub-command reset-sync-time.
