regulators: Add hardware presence service
The regulators application needs to determine whether hardware is
present or absent. Some voltage regulators are optional, and
configuration should only be performed if the regulator is present.
Add a new class to obtain hardware presence data from the D-Bus
xyz.openbmc_project.Inventory.Item interface.
Also define an abstract base class and a mock implementation to enable
use of gmock in test cases related to hardware presence.
Tested:
* Tested where inventory path is present
* Tested where inventory path is not present
* Tested where inventory path is invalid and results in an exception
* Verified that mock implementation could be used in a gmock test case
* Full test plan available at
