[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.
