Update readnoise monitor to use django database models

[york-stsci]

This PR is a test of updating one of the monitors (readnoise) to use the django database model, both for insertion and retrieval. It also adds general documentation describing the process.

This looks ok to me, as someone who is not a Django model expert. And I'm assuming there's no issue with defining the models for all of the monitors in this PR, even though the monitors themselves are not yet switching over to use them.

I do think the Django environment variable setting and call to setup() probably need to be in an if clause so that they're not run on RTD or GA.

The models were actually all defined in a previous (and merged) PR. This PR touches all of those files because, when I found out that I needed to change the (incorrect) data types that django had assigned to array fields, I just did it for all the monitors rather than stop with readnoise.

This looks good to me with only a mispelling in the doc.
Aside from readnoise.py, I did not dive deep into the monitor_models as they will be changing.

Especially excellent work with the documentation update, thanks for taking the time to do that!
