    Note: When migrating from count() to countDocuments() the following query operators must be replaced:
    
    +-------------+--------------------------------+ | Operator | Replacement | +=============+================================+ | $where | $expr | +-------------+--------------------------------+ | $near | $geoWithin with $center | +-------------+--------------------------------+ | $nearSphere | $geoWithin with $centerSphere | +-------------+--------------------------------+
    Parameters:
    
    clientSession - the client session with which to associate this operation
    
    filter - the query filter
    
    options - the options describing the count
    
    Returns:
    
    a publisher with a single element indicating the number of documents
