This commit consists of the following:
1) The kafka messaging proxy in Twisted python for adapters
2) Initial implementation and containerization of ponsim OLT adapter
and ponsim ONU adapter
3) Initial submission of request and response facade in both Twisted
python and Go Language
4) Initial implementation of device management and logical device management
in the Core
5) Update to the log module to allow dynamic setting of log level per
package using the gRPC API
6) Bug fixes and minor changes
