Code monitors: add (currently unused) include_results option

Created by: camdencheek

This adds an option to return the result contents in action payloads. It is currently not yet used, but it adds the databse and GraphQL layer to start building off of.

Test plan

I will add tests for this once it's actually hooked up to the payload generation. Right now, these changes should not affect any functionality, and that is checked by existing tests.
