Anonymous reminder

[q-wertz]

Summary

Currently it is always noted who set up the reminder in the reminder message. In some cases it would be convenient to have an anonymous version which only shows the message but not who created it.

Describe alternatives you've considered

Add a system user with the name of the team. But would then require to always ask the admins for a new reminder.

Additional context

e.g. an --anonymous flag in the command
