Add maxLogFiles option (#6296)

https://community.parseplatform.org/t/server-log-retention/867/2

Maximum number of logs to keep. If not set, no logs will be removed. This can be a number of files or number of days. If using days, add 'd' as the suffix. (default: null).

I'll run this in production for a few days. I assume it works.

Useful for saving disk space.
