Echo endpoint

Work in progress

This warning will be removed once this page has passed testing.

Sometimes you need to test a client's ability to respond to various message or error/status codes. It may be difficult to purposefully generate a 500. In these cases you can enable HY_ADD_ECHO. Then you can PUT to /_echo a JSON as follows:

{
  "status_code": ###,
  "message": {...}
}

This produce a response with status code as specified, with the message value as the body. It also goes through the service logging system, so you can test receiving emails on 5xx, etc. (or however you choose to extend the logging)
