[edk2-staging][PATCH v3 09/15] edk2-staging/RedfishClientPkg: Update RedfishLib


Nickle Wang
 

RedfishLib has no capability to return HTTP header in response.
However, feature driver needs to know the information like "ETag" or
"Location" in HTTP response header per Redfish specification. Add
corresponding function to return HTTP header in response data.
