Improve serverless.yml / cloudformation stacks across services

[zhammer]

Ideally the entire morning cd collection of services could be totally redeployed directly from their serverless.yml files. A few current issues / opportunities for improvement

• [ ] Some services had manual actions performed from console that could be included in their cloudformation
• [ ] Some services have messy, hard-coded values where cloudformation intrinsic functions could be used
  • referring to references within their stack, or
  • referring to values that could be imported from other stacks (like sns topics)
• [ ] Some services have big chunks of serverless.yml config that could be extracted into sub files for clarity
• [ ] Some services had manual actions performed that couldnt easily (or at all) be included in their cloudformation these can be ignored at first

It'd be nice to do some cleanup on this overtime. Learning better cloudformation setup (via serverless) would be nice overall too
