add-fixed-ip doesn't update nwfilter in libvirt driver

[Chet Burgess]

When using nova add-fixed-ip the result is we have multiple ips per mac address. This leads to needing multiple IPs addresses in the libvirt nwfilter. We need to support this during initial XML generation/regeneration and add hooks to dynamically updated the nwfilter in libvirt when the IP is added.

    Refactor nwfilter parameters

    * libvirt < 1.0.1 does not allow dynamically updating filter
      parameters inside an interface block of theinstance XML. To
      address this we move the nwfilter paramters from the instance
      XML to the per-instance base nwfilter.

    Relates to bug #1124722

    Make add-fixed-ip update nwfilter wth in libvirt

    Add inject_network_info to the libvirt driver so that the
    add-fixed-ip call will trigger a refresh of the nwfilters.
