This commit consists of:
1) Dockerizing the netconf server
2) Update proto2yang to support module imports
3) Provide a set of yang modules derived from the proto files in voltha.
   These files as well as the slight mmodifications to the proto files are
   provided in the experiments/netconf/proto2yang directory
4) Code to automatically pull proto files from voltha into the netconf server,
   compiles them and produce the yang equivalent files.
5) Add a getvoltha netconf API to provide voltha state information (basic at
   this time).  There is potential to make this generic once we experiment
   with additional APIs
