VOL-281: OfAgent integration in swarm cluster
- Auto connect/reconnect of agent with a voltha instance
- Survives and cleans up after a voltha disconnect
- Added new compose files to start ofagent and onos in swarm cluster

Amendments:
- Fixed logs to have uniform format
- Removed instructions to start/stop ONOS service in cluster scripts
- Added missing change in local handler to exit streaming rpc calls
  after ofagent termination
- Renamed references from voltha to vcore where necessary
