Always setup libvirt for tap devices when using Neutron
This logic has been tied to OVS since it was introduced in [1] and
revised in [2]. However, many other backends may use tap devices that
aren't related to OVS, such as Calico[3] and Linux Bridge after [4]
merges.
This patch just removes the dependency on OVS specifically so
/dev/net/tun is added to cgroups whenever any Neutron backend is used.
This is done in other deployment tools like Juju[5] so it's not
unprecedented.
