[lib] Create veths using systemd opnfv-fuel units
Create 2 systemd services on the jumphost that will handle veth
pairs creation, respectively adding them to virsh/real bridges.
This allows us to set docker containers restart policy to 'always',
enabling persistent Salt Master/MaaS containers across jumphost
reboots.
NOTE: libvirt creates virtual networks async, hence the need for
retrying hooking veths to them.
