APCs rpdu's total energy/power metric is missing

Per default we only collect load from all phases

but the total load is missing.

rPDU2GroupTotalPower
.1.3.6.1.4.1.318.1.1.26.11.2
Getting this OID will return the total power consumption of the Rack PDU
Network Port Sharing (NPS) group devices in hundredths of kilowatts.
Queries to guest units in an NPS group are not applicable and will
return 0.

rPDU2GroupTotalEnergy
.1.3.6.1.4.1.318.1.1.26.11.3.0
Getting this OID will return the total energy consumption of the Rack PDU
Network Port Sharing (NPS) group devices in tenths of kilowatt-hours.
To reset the energy meters for each of the Rack PDU devices that contribute
to this value, see the rPDU2GroupEnergyReset OID.
To view the start time for each of the Rack PDU device energy meters that
contribute to this value, see the rPDU2DeviceStatusEnergyStartTime OID.
Queries to guest units in an NPS group are not applicable and will
return 0.
