Add Verify_Redfish_BMC_PowerOn_With_OCC_State case
Add Verify_Redfish_BMC_PowerOn_With_OCC_State case

There is case to test the BMC to power on host,
Verify_Redfish_Host_PowerOn, in which it verifies that the OCC state is
active and `PowerConsumedWatts` exists on Redfish.

However, for systems without a total power sensor, e.g. Romulus and
Palmetto, there is no total_power sensor, and thus there is no
`PowerConsumedWatts` property on Redfish.

Add a case that only powers on the host and verify the OCC state, but
not check the `PowerConsumedWatts` property, so that it could be used to
test on systems without total power sensor.

Tested: Verify the case Verify_Redfish_BMC_PowerOn_With_OCC_State
        passed on Palmetto and Romulus.
