Server communication HTTP vs Web sockets

Should we keep HTTP or move to Web sockets?

The benefit of Web sockets is that we can easily push data from server to client, e.g. "model update" or even for hyper parameter tuning #151. These features are more complex with HTTP.

The problems with web sockets are mainly the overhead it adds, although this might be negligible?

Work wise it is worth it given the benefits that we mentioned.
