glusterd/mgmt_v3: Initating complete synctask on glusterd

glusterd mgmt_v3 is nothing but a complete synctask approach
for glusterd to function. The commands making use of this
won't be using the op-state machine to inject events and
will be using the synctask framework to perform operations
across all nodes in the cluster. This patch defines the
program and the handlers used.
