glusterd: fix bugs of syncop for operations
* free the stack created for synctask * use different key than 'operation' in dictionary as thats being used already by other glusterd operations * send proper frame to 'rpc_clnt_submit()' API, as it gets used internally * also make sure to destroy the above frame in all _cbk() * move everything specific to synctask into one file, so it is easy to maintain Change-Id: Ia1a4414fffec6f9e51700295947eea4a2104a8c2 Signed-off-by: Amar Tumballi <amarts@redhat.com> BUG: 805802 Reviewed-on: http://review.gluster.com/3000 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Krishnan Parthasarathi <kp@gluster.com>
