    Instances with NUMA will be packed onto hosts

    This patch makes the NUMATopologyFilter and instance claims on the
    compute host use instance fitting logic to allow for actually packing
    instances onto NUMA capable hosts.

    This also means that the NUMA placement that is calculated during a
    successfull claim will need to be updated in the database to reflect the
    host NUMA cell ids the instance cells will be pinned to.

    Using fit_instance_to_host() to decide weather an instance can land
    on a host makes the NUMATopologyFilter code cleaner as it now fully
    re-uses all the logic in VirtNUMAHostTopology and
    VirtNUMATopologyCellUsage classes.
