glusterd/geo-rep: Looks for state_file and pid-file in gsyncd_template.conf

If entries like state_file or pid-file are missing in the gsyncd.conf
or if the gsyncd.conf is also missing, glusterd looks for the missing
configs in the gsyncd_template.conf

status will display "Config Corrupted" as long as the entry is missing in
the config file.  Missing state-file entry in both config and template
will not allow starting a geo-rep session.

However stop force will successfully stop an already running session,
if the state-file entries are missing in both the config file and
the template, as long as either of them have a pid-file entry.

if the pid-file entry is missing in the gsyncd.conf file, starting a
geo-rep session will not be allowed.

if the pid-file entry is missing in an already started session, then
stop force will fetch it from the config template and stop the session.

if the pid-file entry is missing in both the config and the template,
stop force will fail with appropriate error stating pid-file entry is missing.
