Description

LMSEstimator is currently used in Solr index to avoid network traffic in result size estimation.
It might be beneficial to reuse it for the same scope within Oak ES, by moving LMSEstimator into oak-search.
Note that this implies oak-solr-core will start depending on oak-search which was anyway planned for a while already.
