Pushed Switch Mastership Events into the Topology event channel.
Needed for ONOS-1729
For now those events are not used.

Also, added new TopologyElement attribute type: TYPE_ALL_LAYERS
which applies to the Mastership Events.

NOTE: Currently, those events are intercepted within the
Floodlight Controller.java class. The interception point might be moved
once it becomes clear whether the event origin should be the mastership
election mechanism or the "role change request" accepted by the switch.
In addition, the interception point needs to be moved/ported as appropriate
once we move to the newer 1.3 OpenFlow driver implementation and eventloop.
