Provide more info about created Resources via logs or outputs section

[zeljkoX]

(Nice to have) When creating specific resources users could find useful to see additional data via logs or outputs section.

For example when creating Relayer it would be useful to display its address as part of the logs(like we do for the id).

Additionally, we could add support for outputs section so users could reuse resources info as part of the other scripts.

Example

  Outputs:
    MyRelayerAddress:
      Value: !Ref relayer-1
