hypervisor: add state support

phosphor-state-manager support a new optional package,
phosphor-state-manager-hypervisor. IBM plans to include this package on
their system to monitor and control the hypervisor firmware running on
the system.

Since this package is optional, this patch set is written to just ignore
any errors associated with the package and not report hypervior state
in these cases.

Tested:
- Verified when phosphor-hypervisor-state-manager package is not
  installed that Redfish API returns same info it does currently
- Verified when phosphor-hypervisor-state-manager was installed that the
  hypervisor state was returned correctly.
- The redfish validator was run on the final patch in this series
