Make our preconnect logging clearer #3483
Description
If something goes wrong in our preconnect stage, the Agent log output looks something like:
Received HTTP status code Unauthorized with message {}. Request content was: [{"high_security":false}]
Even though that's technically correct (logging the payload we sent), this makes it seems like High Security mode has something to do with the failure when it doesn't (There's a separate status code for that). This has confused customers in the past.
