[Moshe Levi]

Talking on IRC the issue relates to this code:
https://github.com/openstack/nova/blob/master/nova/virt/libvirt/vif.py#L483

When using ubuntu packages you get compute.filters not network.filters (quite correctly), and it turns out this is in the wrong one.
i.e. this is needed for neutron + nova, when the nova-network package is not installed.

Thats assuming network.filters really is meant to be only for nova-network, and its not clear thats the case right now, although that probably was the intention originally.

    Move ebrctl to compute.filter.

    Currently ebrctl is network.filters, but the utility is
    used by libvirt in nova compute, as part of a Mellanox vif driver.

    The ubuntu packages install network.filters with the nova-network package.
    But this vif driver only works with Neutron.

    To help fix that, this patch move it to compute.filters to ensure it is
    always installed with Nova.
