geo-rep: Support for using Volinfo from Conf file

Once Geo-replication is started, it runs Gluster commands to get Volume
info from Master and Slave. With this patch, Georep can get Volume info
from Conf file if `--use-gconf-volinfo` argument is specified to monitor

Create a config(Or add to the config if exists) with following fields

    [vars]
    master-bricks=NODEID:HOSTNAME:PATH,..
    slave-bricks=NODEID:HOSTNAME,..
    master-volume-id=
    slave-volume-id=
    master-replica-count=
    master-disperse_count=

Note: Exising Geo-replication is not affected since this is activated
only when `--use-gconf-volinfo` is passed while spawning `gsyncd
monitor`

Tiering support is not yet added since Tiering + Glusterd2 is still
under discussion.

Fixes: #396
