Multiple notification targets of the same kind can now be defined

You can now define multiple notifications targets of the same type with different configurations.

This is useful when you want to define different notification conditions for different targets.

    - rooms:
        - <account>:<token>#failures
      on_success: never
      on_failure: always
    - rooms:
        - <account>:<token>#successes
      on_success: always
      on_failure: never
