Various bmv2 changes to reflect onos-bmv2 v1.0.0 (onos1.6 cherry-pick) 

Most notably:
- Updated repo URL and commit ID to official onos-bmv2 fork
- Removed ugly string-based table dump parser, now there's
	a proper API to retrieve table entries (added support in
	Bmv2DeviceAgent)
- Removed unused arguments in packet-in API
