Bluesky queueserver

[ksunden]

Very early draft, just opening here to have an easy place to see the changes.

Lots of code can likely be deleted here.

Next steps

• Buttons for starting/interrupting queue
• Ability to enqueue plans
• UIs for plans
• Better use of status for more intelligent UI refreshing/limiting large requests.
• Databroker tab (using bs widgets?)
• Live plotting (via databroker, zmq, or kafka, not sure?)
• How to handle uploading to gdrive/autogen plots
• Handling of updates to autonomic system (plans?, sidechannel?)
