Pipeline aggregations like `stats_bucket`, `sum_bucket`, and `percentiles_bucket` only operate on buckets that have multiple buckets. This adds support for those aggregations to `geo_distance`, `ip_range`, `auto_date_histogram`, and `rare_terms`. This all happened because we used a marker interface to mark compatible aggs, `MultiBucketAggregationBuilder` and it was fairly easy to forget to implement the interface. This replaces the marker interface with an abstract method in `AggregationBuilder`, `bucketCardinality` which makes you return `NONE`, `ONE`, or `MANY`. The `bucket` aggregations can check for `MANY`. At this point `ONE` and `NONE` amount to about the same thing, but I suspect that'll be a useful distinction when validating bucket sorts.
