ONOS-6468 Fix for race condition between compilation and installation complete state.
- Fix for a bug where intent compilation complete state,
can overwrites intent installation complete state,
if intent installation completes before compilation complete state is written to the store.
- Introduced internalState version on IntentData,
which is effectively mutation count, in order to avoid
batch write of compilation result overwriting installation result
