* Notifier interaction: add events to notifiers in order to receive commands also from a connected notifier.

Implemented only for Telegram at the moment.
 - list of accepted commands is the same used in command line
 - check the correct origin of the message looking at chat ID
 - accept the flag 'c.notifiers.telegram.interactive' (default = false)
   to enable/disable this feature

This commit provides a possible solution for feature request #1550
