Add a bare-bones struct for parsing the output of `ip -details -json
link show`. Currently we only require the name of the interfaces as
well as its altnames for transparently supporting altnames in the
firewall.

Notes:
There is probably a better place than proxmox-ve-config for this. I've
put it here for now, since we have some network-related stuff in this
repository already. Mid to short-term it would be better to extract
all this stuff into either a separate crate or proxmox-sys. For this
POC its fine.
