Subject: [EXTERNAL] [PATCH v2] RedfishPkg/RedfishRestExDxe: return HTTP status code to caller.


**CAUTION: The e-mail below is from an external source. Please exercise caution before opening attachments, clicking links, or following guidance.**

Return unsupported HTTP status code to caller so caller can handle
HTTP error status code. Current implementation only return EFI error
to caller. Without knowing the HTTP status code, caller has trouble
to handle HTTP request failure.
