[VOL-2241] Python 3 refactor of pyvoltha
Majority of work was manual fixes to bytes and strings types, which are
different in py3, but same in py2. As the OMCI library does a lot of
these comparisons and scapy then renders packets, this was frequently
nontrival to debug.
Also:
- Removed grpc dep which wasn't being used, not py3 compatible
- s/Alarms/Events/ to work with protobuf changes per VOL-2224
- Automatic fixes via modernize tooling
- Removed unused OrderedWeakValueDict code
- Removed frameio send_frame specific to Darwin (MacOS), which had no
corresponding linux code
- Use library functions for hex and unicode conversions
- Various other cleanups and fixes (EOL whitespace, etc.)
Also more (Matt):
- handle stringify better, check if already string
- use binary string for binary work
- import new thread paths
- update requirements.txt for newer libraries needed with newer python
- return proper tuple for unpacking
- bytes string formatting fixed
- fix mock task unit test
Even more (Zack):
- Python 2/3 compat for _thread by using 'future'
- Bump version to 2.3.0

This facade handles kafka-formatted messages from the Core, extracts the kafka
formatting and forwards the request to the concrete handler.
