    Adds hypervisor_version_requires (ImagePropertiesFilter)

    This is to prevent instances with newer tools from being
    provisioned on older hypervisors.

    Added comparison of hypervisor version from the
    compute-node and image metadata in the image properties
    filter.

    In host scheduler image_prop_filter, the hypervisor_version_requires
    image properties, if available, is compared to the host_state's
    hypervisor_version, if available.

    hypervisor_version_requires should be added on the image
    as metadata and should have a operator and version value.
    Examples : ">=6.0", ">6.0, <6.2", ""!=6.1".
