DT-1143: Passthrough APIs for support requests and content uploads

Summary

This PR adds two APIs that act as passthroughs to Zendesk's Request API service. The intention here is to approximate what the UI expects in terms of response codes and objects. There are some minor changes to reduce the scope of what the UI needs to do in terms of parsing responses, but in general, it hews fairly close to what Zendesk returns.

Testing

To test sending a real ticket to Zendesk, update your local consent.yaml config value:

services:
  ...
  activateSupportNotifications: true

The Support APIs are not authenticated so can be easily tested in swagger.
