    Cells: Add filtering and weight support
    
    This adds filtering and weighing support to the cells scheduler.
    
    Adds the following config options to the 'cells' group:
    
    scheduler_filter_classes -- list of filter classes
    scheduler_weight_classes -- list of weight classes
    
    Adds a couple of weighing modules as defaults (which removes the random
    cell selection):
    
    ram_by_instance_type: Select cells with the most capacity for the
    instance type being requested.
    weight_offset: Allows modifying the DB to weight a particular cell
    (useful for disabling a cell)
    
    Adds a filter class that allows specifying a scheduler hint to direct a
    build to a particular cell.
