  To: devel; +Cc: Abner Chang, Igor Kulchytskyy, Nick Ramirez

This library follows Redfish Host Interface specification and use IPMI
command to get bootstrap account credential(NetFn 2Ch, Command 02h)
from BMC. RedfishHostInterfaceDxe will use this credential for the
following communication between BIOS and BMC.
