Configuration options for notifications

[aronmolnar]

We have a request from a customer to allow disabling notifications globally, per user, or per project.

Globally
Disabling notifications globally and installation-wide should be rather easy to implement via settings.

Per User
Disabling them per user might introduce some complexity:

• Specify them per user?
• Per group (there are no groups, currently)?
• Who decides which user receives notifications?
  • The user himself?
  • The user manager?

Users already have the possibility to mute notifications:

This setting is stored in the browser's Session Storage.
I'd rather not introduce such a fine-grained control due to complexity.

Per project
This could be possible by introducing a project setting which "mutes" notifications from this project.
This, again, might introduce some complexity:

• Can any project member mute a project or is a special permission necessary?
• Is there an audit trail who muted (and unmuted)?
• Is it possible to disable muting projects installation-wide?

I also believe that this rather shouldn't be implemented.
