On some Redfish POST requests, the go-redfish library provides more
error messages. This changes adds the capability to screen for those
messages and provide them in a single, end user-consumable error.
NOTE: due to some malformed responses, some errors may not get more
information. A future change will further inspect the JSON to retrieve
those.
