update impl which uses widowx-srv

[youliangtan]

Summary:

Dependencies are usually a pain, especially when it involves localized hardware. Thus, instead of interacting with the robot lib api diractly, the PR enables user to run widowx as a server and client architecture. The widowx robot abstraction is kept within the docker container, and services are exposed as TCP ports. User can then run a ML/RL script in a seperate conda env (same or remote), interact with the minimal widowx client api.

• Depends on this https://github.com/rail-berkeley/bridge_data_robot/pull/5
• Edgeml framework: https://github.com/youliangtan/edgeml

Note:

• The server still retain the use of previous 'widowenv' gym compliant api, which might not be the best way to do. Will require further cleanup effort in the future.
