    Add support for fitting instance NUMA nodes onto a host

    This commit adds the methods needed to enable fitting instances onto
    NUMA nodes. It adds fit_instance_to_host() method to the
    VirtNUMAHostTopology class that will do the fitting returning the
    instance topology with it's cells assigned to the cells of a given host.

    This method will be used in the scheduler and claims and will obsolete
    the need for claim_test method which will be removed in subsequent
    commits.

    It is worth noting that after we transition filter and claims to use the
    methods added to this patch - it will no longer be possible for an
    NUMA-aware instance to be over-committed against itself no matter what the
    over-subscription ratios are.
