refs #10790
- The code was moved out of controllers to reduce the number of coupling points between the API controllers and "frontend" services
- A nice side effect of this move is a decreased amount of code that will need to be maintained and reusability between existing controllers
- Calling just a few methods from frontend services on API level makes it easier to abstract fronted away from API
