Initial setup for BANZAI-at-site

[timbeccue]

Description

Set up banzai to run in a self-contained docker-compose configuration. This includes a rabbitmq queue that listens for incoming images, which are reduced and saved to a local directory. The local banzai should reference LCO's AWS banzai db (the readonly clone) for the calibration files it uses.

Tasks

• get the existing banzai docker-compose running, and ensure readme is up to date
• set up a listener queue
• mimic site software instrument agent: make a script that adds test files to the listener queue
• connect to remote banzai for calibrations
• add configurable path to save completed reductions
• Everything works: "instrument agent" script adds files, which get reduced using calibrations from AWS, and are finally saved to disk

Future work, not scoped here:

• shipping anything to an archive
• local db for banzai to keep track of completed reductions (but not calibrations)
