* [edk2-redfish-client][PATCH 6/6] RedfishClientPkg: Introduce RedfishConfigLangMap driver

To: devel; +Cc: Abner Chang, Igor Kulchytskyy
Introduce Redfish configure language map driver. This driver keeps the
mapping between configure language and Redfish URI for internal use.
This saves the communication time between feature drivers and Redfish
service. It also provides the history records so that feature drivers
can do provisioning, consuming and updating efficiently.
