Add additional Redfish Manager properties

This commit adds the following inventory properties for the
BMC resource:

a) LocationCode, a free form, implementation-defined string
to provide the location of the BMC. This is needed so an
implementation can identify the BMC via system diagrams and such.

b) Model, maps to a CCIN/Card ID for IBM's implementation,
is a string for the manufacturer's part model. For IBM's
implementation, it is a four-digit value assigned for each
possible FRU.

c) SparePartNumber, also field-replaceable unit (FRU) Part Number,
is a part number that identifies the FRU for replacement
specifically ordering of a new part.

For some manufacturers the BMC is soldered down, this is not the
case for all manufacturers. For our systems, the BMC can be
replaced and these properties are essential to locate and replace
the BMC.

Redfish validator has been executed on this change and no new
error was found.
