feat: read the node's listening sockets through napalm-device-types

ProxmoxDriver mixes in ListeningSocketsMixin (napalm-device-types 2.4.0)
and carries its command over the exec path, which runs as root either
way: whether pveproxy, a Ceph manager or anything else on the node listens
on an address reachable from outside it.

For netOrk#658.
