Missing details in Error Payload

When an ClientV3Exception is thrown there is more details available in the message than exposed through the Error object. Specifically it would be useful to get the content test_mode_info which had additional details which in this case was bad YAML provided in the manifest.yml. The only way to get these details currently is to search through the cloud controller logs but I assume they come back in the JSON payload that the cf java client could sift through and provide on the Error class.

Beginne damit, ClientV3Exception und die Verarbeitung der Error-Payload im cf-java-client nachzuverfolgen, wobei die JSON-Antwort und das Beispiel für test_mode_info in diesem Issue als Referenz dienen. Der serverseitige Kontext befindet sich in errors_controller.rb, und der Fehler betrifft das Parsen von manifest.yml. Erledigt ist die Aufgabe, wenn das Error-Objekt die zusätzlichen Details von test_mode_info bereitstellt, statt Cloud-Controller-Logs zu erfordern.
