📄 Description

Description of the issue/feature this PR addresses:
Our environment sends over 50,000 emails per day. Even with dividing dovecots and postfix log and daily rotate, you'll still end up in 80MB log files easily. This causes huge CPU spikes the bigger the log file gets. Eventually this will cause all of your system cores to be under extremely high load causing the whole system to be slow.

This is also shown in this discussion:
https://github.com/modoboa/modoboa/discussions/2031

and this isuse:
https://github.com/modoboa/modoboa/issues/1187

For context, here's the systems load over 30 days - you can clearly see when we switched to once per day which is why I believe the hint I've added is very useful for others.

Current behavior before PR:
Logparsing was entirely missing from the crontab. No hint of possible performance issues.

Desired behavior after PR is merged:
Modoboa also offers log parsing which was not yet reflected in the cron job sample of the manual installation part.
As log parsing can be fairly CPU intensive there's also a hint for that.
