Description

If the agent can't parse the response to a registration operation, it raises an exception. The response message is lost.

1. controller must check HTTP response
2. The controller needs to catch parse exceptions exception, log the response.
3. Maybe add a check for a 0 byte response too.
4. looking at AgentResource, we should make sure that all failure codepaths log, and, if it doesn't break agent version compatibility, include error strings in the JSON Response, for container logs
