Bad Request from supervisor should be error

[mdegat01]

Proposed change

If an API call is made to Supervisor and it cannot process it due to invalid input or a handled issue that occurred with the particular resource it responds with a 400 (Bad Request) type response. This is an error, the API call was not processed successfully. Core should treat it like an error and raise an exception like it would or any other non-200 type response.

Currently this causes a number of problems. For example, repairs created by supervisor always disappear when the user applies the repair even if it wasn't actually applied successfully. Or when a service call results in an API call to supervisor with invalid input but appears to have been processed successfully:

I'm not entirely sure why Bad Request was originally given a pass on raising an exception so I don't know exactly what issues this change could cause. Hopefully if someone does they can comment and we can work on those. Logically though it doesn't really make sense to me, a 400 response is clearly an error and should not be treated like a success.
