netplug: T5476: rewrite dhclient helper from Perl -> Python
There are two hooks called for bridge, ethernet and bond interfaces if the link-state changes up -> down or down -> up. The helpers are: * /etc/netplug/linkdown.d/dhclient * /etc/netplug/linkup.d/dhclient As those helpers use Linux actions to start/restart the dhclient process in Perl it's time to rewrite it. First goal is to get rid of all Perl code and the second is that we now have a Proper Python library. Instead of checking if the process is running the then restarting it without even systemd noticing (yeah we might get two processes beeing alive) we should: * Add a Python helper that can be used for both up and down (see man 8 netplugd FILES section) * Query the VyOS CLI config if the interface in question has DHCP(v6) configured and is not disabled * Add IPv6 DHCPv6 support MAN page: https://linux.die.net/man/8/netplugd
