Missing ingress handling for some p2p ports

[aasseman]

What I've found missing up to now:

• Erigon's torrent p2p ports
• Heimdall's p2p ports

There needs at least to be NodePorts (optionally) set-up, as well as the possibility to change the port numbers in the software (because of the 30000-32768 limitation on NodePort port numbers).

In general, it could also be interesting to be able to generate LoadBalancers instead, as that would make it smoother to handle the p2p ingresses in managed cloud kubernetes, or when using MetalLB.
