Various Bmv2 protocol refactorings in preparation of the flow rule
translator (ONOS-4044)

- Added new classes for different match parameters (exact, ternary, lpm,
  valid)
- Divided api package in two sub-packages, model (previously under
  drivers) and runtime (old api package)
- Improved Bmv2ThriftClient caching and table entry handling
