Users should be able to throttle their updates

[destan]

Currently if an admin sends 10 messages in an hour then all users would get them in real time. Users should be able to throttle incoming updates for themselves like send me at most 2 updates per hour etc.

Users can activate, change or disable throttling via a telegram command. something like /throttle or /decrease.

After command the bot should sends a set of buttons to users with predefined throttling choices like:

• 1 message per hour
• 2 messages per hour
• 3 messages per hour
• 4 messages per hour

those choices should be configurable via application properties or via application database
