Various changes in BMv2 driver and provider modules

Driver notable changes:
- Implemented new behaviors, removed deprecated ones
- Removed flow rule translator classes (now under protocol module)
- Improved FlowRuleProgrammable: now it uses BMv2TableEntryService
	to lookup/bind flow rules with BMv2 table entries, retrieves flow
	statistics, better exception handling when adding/replacing/removing
	table entries.
- Improved PacketProgrammable: better exception handling and logging

Provider notable changes:
- Bmv2DeviceProvider: detects and notifies device configuration
	changes and reboots to Bmv2DeviceContextService, added support for
	periodic polling of port statistics
- Bmv2PacketProvider: implemented workaround for OutboundPackets with
	flood treatment
