regulators: Add VPD service
The regulators application needs to obtain VPD (Vital Product Data)
keyword values.
Sometimes regulator configuration and monitoring varies depending on
hardware type or version. VPD keyword values can provide this
information about the hardware.
Add a new class to obtain hardware VPD from the D-Bus
xyz.openbmc_project.Inventory.Decorator.Asset interface.
Also define an abstract base class and a mock implementation to
enable use of gmock in test cases related to VPD.
Tested:
* Verified VPD values were successfully obtained from D-Bus.
* Verified VPD values were cached.
* Tested where object path was invalid.
* Tested where keyword was invalid.
* Verified cached VPD values were cleared when machine powered on.
* For the complete test plan, see
