Work toward fixing ONOS-1031: Removed modules FlowManager and the old TopologyManager

 * Removed module FlowManager
 * Removed module TopologyManager (in directory ofcontroller/topology)
 * Removed corresponding state in HazelcastDatagrid.java
 * Removed corresponding REST call to obtain the Hazelcast datagrid state:
   GET /wm/onos/datagrid/get/map/{map-name}/json
    where "map-name" is: all, flow, flow-entry, topology
