CORD-394 Purge group/flow store when device goes offline
Stage 1: (this commit)
Add a component config purgeOnDisconnection, which is false by default.
When set to true, GroupManager and FlowManager will purge groups/flows
associated with a device when the device goes offline.
Stage 2: (upcoming commit)
Enable these configs in SegmentRoutingManager
Clean up group related information in SegmentRountingManager
