    Fix bug to filter_scheduler

    In https://docs.openstack.org/nova/latest/configuration/config.html#filter_scheduler.max_instances_per_host
    refers to the "num_instances_filter" but that's the name
    of the python module, not the actual filter.
    So the config option help text should be updated to use
    the actual filter names that would go in the 'enabled_filters'
    option, not the python module in which those filters live.
