Always request hex via the post to API mechanism (#3149)

* Always request hex via the post to API mechanism

- enables logging of requests for older versions via API rather than GA,
- gives flexibility in future if we need to return alternative hex files for any reason.

* The URL for the hex is now returned by the API

* Only apply these settings if expertmode is enabled.
