HVDC power port types

[molusk]

Hi,

We received new routers in our lab and some have a new kind of power ports I can't find in Netbox.

May be the name Nokia and Huawei use is not the standard one, they call it either HVDC or HVDC3.

See figures 6-8, 6-9 and 6-10.

If it is a type unknown from Netbox, should I do a PR after editing choices.py or just open an issue ? I read somewhere cable types are completely static, does it mean this file is the only one to alter ?

Thanks in advance for your help.
