Enhanced !command logging

[jacob-card-howe]

Add logging surrounding what users entered in !create, !terminate, and !start / !stop commands.

• Should log Discord User ID
• Should log time that command was entered into Discord

I think a cool interface for this might be something like !log <command (start, stop, create, terminate)> <start time> <end time>. So the syntax in practice would be something like !log terminate 2022-01-07:16:45 2022-21-07:16:45 to find all logs for the !terminate command between July 1st and July 21st, 2022 🤷🏻

As for implementing the log itself, I wonder if we should / could make use of AWS Cloudwatch, or if we should utilize Discord's messages. I think with the latter there's a limitation on how many messages we can look through.
