> To persist single permission change, it needs to combine multiple things in a 
> single transaction:
> * Doing the actual operation (priv change)
> * Updating notification ID.
> It is important to do this in a single transaction to guarantee that 
> notificationID handling is atomic. Current code structure doesn't allow for 
> that.
> So we need to pass extra transaction code to SentryStore functions or figure 
> out a generic way to do this.
