Various improvements to PI group handling

- Moved group translation logic to core service
- Removed dependency on KRYO
- Fixed bug where tratments with PI instructions where not supported if
	an interpreter was present
- Fixed bug where action profile name was not found during protobuf
	encoding (always perform P4Info lookup by name and alias)
- Improved reading of members by issuing one big request for all
	groups
