Async/streaming gRPC client/server proto

This experiment was to fine-tune how we can implement
async gRPC client and server code inside a Twisted
python app.

Change-Id: I945014e27f4b9d6ed624666e0284cc298548adb3

Major cleanup of openflow_13.proto

Change-Id: I4e54eaf87b682124ec518a0ade1a6050a6ec6da8

Relocated openflow_13.proto to voltha

Change-Id: I66ae45a9142d180c2c6651e75c7a1ee08aef7ef8

Removed forced utest from make build

Change-Id: If0da58e9d135ebde6ca68c3316688a03a7b10f2f

twisted openflow agent first pass

Change-Id: Ibe5b4727ccfe92e6fd464ccd3baf6275569ef5d3

store openflow derived files

Change-Id: Ib3e1384bb2ca2a9c0872767f7b793f96b0a154e2

Minor cleanup

Change-Id: I1280ed3acb606121b616a0efd573f5f59d010dca

Factored out common utils

Change-Id: Icd86fcd50f60d0900924674cbcd65e13e47782a1

Refactored twisted agent

Change-Id: I71f26ce5357a4f98477df60b8c5ddc068cf75d43

Relocated openflow agent to ofagent

... and preserved obsolete working (non-twisted) agent under
~/obsolete, so we can still run the olt-oftest and pass tests,
unit the new twisted based agent reaches that maturity point.

Change-Id: I727f8d7144b1291a40276dad2966b7643bd7bc4b

olt-oftest in fake mode works with new agent

Change-Id: I43b4f5812e8dfaa9f45e4a77fdcf6c30ac520f8d

Initial ofagent/voltha operation

Change-Id: Ia8104f1285a6b1c51635d36d7d78fc113f800e79

Additional callouts to Voltha

Change-Id: If8f483d5140d3c9d45f22b480b8d33249a29cd4e

More gRPC calls

Change-Id: I7d24fadf9425217fb26ffe18f25359d072ef38fa

Flow add/list now works

Change-Id: Ie3e3e73108645b47891cef798fc61372a022fd93

Missed some files
