Data pruning

[pipermerriam]

What is wrong

Glados accumulates a lot of data that isn't necessarily useful over a long timeline.

• old audits
• old census records
• old ENR records

How can it be fixed

Probably be nice to have a glados prune command that could be used with a few flags to prune data that is older than a certain time horizon. A nice version of this command would maybe have some comfirmation prompts (bypassable via CLI flags) that warn how many rows are going to be deleted, as well as good console logging/messaging that show progress.
