[SparseIndex] Set default user experience sparse index #17966
Description
Is your feature request related to a problem? Please describe
As part of #17710 we evaluated performance of skiplist, we see IndexSortSortedNumeric query performing same irrespective of skiplist when bkd is disabled. But we saw regression in DateHistogram aggression when BKD is disabled. As part of #17964 we will evaluate and implement skiplist for aggregation queries. Based on performance of these changes we can decide to create an index setting which will be used to set default user experience of sparse index and configure skiplist and bkd.
Describe the solution you'd like
Based on results of #17964, we will introduce an index setting and we will make changes in field mappers - DateFieldMapper, NumericFieldMapper, BooleanFieldMapper etc. with this indexSetting which will configure skipList list and BKD for doc_values.
