hypervisor: add support to turn on

If the customer has requested the hypervisor stop at its Standby state
vs. booting all the way to Running, then a mechanism is needed to
request the hypervisor boot to Running. A common use case for IBM is
the system user has requested the hypervisor stop at Standby so some
manual debug can be performed and then they want to move the hypervisor
into the Running state so they can boot their operating system.

Asking the hypervisor to stop at Standby is done via the
BootSourceOverrideEnabled and BootSourceOverrideTarget properties under
the redfish/v1/Systems/system.

Utilize the ComputerSystem.Reset action for this. Similar to how
redfish/v1/Systems/system/Actions/ComputerSystem.Reset is utilized for
the overall system, implement a limited subset of it for the hypervisor
object.

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 Actions field was filled
  in, and a post to the Action with ResetType set to "On" was correctly
  propagated to RequestedHostTransition
- Verified that an invalid ResetType (i.e. "Off") returned the
  appropriate "invalid parameter" error message to the Redfish API
- Verified no new errors logged by Redfish validator on system with this
  hypervisor package installed

- Verify resource not found when hypervisor not enabled
curl -k -H "X-Auth-Token: $TOKEN" -X POST https://${BMC_IP}/redfish/v1/Systems/hypervisor/Actions/ComputerSystem.Reset -d '{"ResetType": "On"}'
