Markos Chandras 49309c4a92 Always create containers with fixed MAC addresses

Patch I0d83fd4895d4c5beaf5a84a239c1a1ed71521dee dropped the ARP=yes
option for networkd because it's not supported by old systemd releases.
This however brings back a problem where the default one sysctl
arp_notify option in the kernel may not correctly set for our use case.
Containers are created with random MAC addresses so we need to ensure
that ARP entries are populated correctly when a container is restarted.
Instead of having to implement some sort of a new workaround on the host,
it's probably better to create all containers with fixed MAC addresses from
now on.
