Support pseduo parameter replacement in more cfn template sections #12
Description
Right now, serverless-pseudo-parameters iterates only over items in the Resources section of the CloudFormation template.
Serverless is not restricted to just the Resources section of CloudFormation, though. Many sections can be specified in the serverless custom resources block, such as custom "Outputs". I'd like to propose checking for any valid section type in the CloudFormation template anatomy and replacing pseudo parameters in all of them.
