Chore: Remove bus from ngalert (#44465)
* pass notification service down to the notifiers

* add ns to all notifiers

* remove bus from ngalert notifiers

* use smaller interfaces for notificationservice

* attempt to fix the tests

* remove unused struct field

* simplify notification service mock

* trying to resolve issues in the tests

* make linter happy

* make linter even happier

* linter, you are annoying
