This commit enables inter-segment search concurrency for numeric terms aggs over long, integer and short field types. It estimates the cardinality by computing the min and max value of the shard using the BKD tree. When the estimated cardinality of the field being aggregated on is lower than the shard size then inter-segment concurrency is enabled.
