When an interface goes down - e.g. cable unplugged - the DHCPv6 assigned IPv6
address is not removed from said interface. We should provide the same behavior
as with IPv4. IPv6 address should be removed and dhcpv6 client restarted once
the interface goes operational up again.

The initial rewrite of vyos-netplug-dhcp-client by me tried to outsmart the
DHCP client implementation by re-using vyos.ifconfig.Interface(). This added
a regression where an interface loosing it's carrier no longer deconfigured
it's IP address. This was a change in behavior form VyOS 1.3.
In addition a bug is fixed as when a VLANs interface parent looses it's carrier
we now also stop the DHCP client process.
This script is now back to simply starting/stopping the DHCP client process.

When an interface is removed from the system also netplug is triggered. It
makes no sense to call vyos.ifconfig.Interface() and update it's configuration
when the interface was just recently removed.
This would in fact re-add an interface temporarily in it's worst case.

Helper scripts should only work on physical interfaces not on individual
sub-interfaces. Moving e.g. a VLAN interface in/out a VRF will also trigger
this script which should be prohibited - bail out early

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
