    Refactor scheduling filters
    
    This changes the scheduling filters to use the code in nova/loadables.py
    to locate filtering classes.  This also creates some base functionality
    in nova/filters.py to be used by both the host scheduler and the cells
    scheduler.
    
    The scheduler_available_filters default has changed to
    'nova.scheduler.filters.all_filters' which is better named compared to
    the old setting of 'standard_filters'.  The old method is still
    supported for those that have put it explicitly in their configs, but
    it's marked as deprecated.
