Log Specific Error Reasons from the VVP API

[austince]

Currently, errors coming from requests to the VVP API are logged with their HTTP reason and message. The message can be vague and not enough information to track down the root issue.

Describe the solution you'd like

There are more fields available on the error response objects, such as the .errors array. We should ensure that array is marshalled if available and include the messages in the error log.

{

  "kind": "ApiValidationException",
  "apiVersion": "v1",
  "message": "Deployment parameters are invalid",
  "reason": "BadRequest",
  "errors": [
    {
      "attribute": "spec.template.spec.resources[taskmanager].memory",
      "message": "must be >= 1000m",
      "reason": "isLower"
    }
  ],
  "statusCode": 400
}
