Subject: [PATCH 309/309] geo-rep: Fix config upgrade on non-participating node

After upgrade, if the config files are of old format, it
gets migrated to new format. Monitor process migrates it.
Since monitor doesn't run on nodes where bricks are not
hosted, it doesn't get migrated there. So this patch fixes
the config upgrade on nodes which doesn't host bricks.
This happens during config either on get/set/reset.
