Support streaming RE waiting hook watcher updates over a new ZMQ topic

[jwlodek]

Resolves #353. Adds an additional zmq topic for streaming RE waiting hook progress updates. Adds additional CLI/config options to enable the feature + a waiting hook compatible class that posts the updates from the RE to zmq. Clients can then use these updates to construct progress bars and the like.

Motivation and Context

Currently, a common piece of feedback from BL staff that use queueserver is that there isn't enough feedback on the state of a scan as it is taking place. Being able to re-create something similar to the bluesky ProgressBarManager by using streamed RE updates should ameliorate this issue.
