[2/2] calcite git commit: [CALCITE-2331] Evaluation of predicate "(A

Posted by jh...@apache.org.
[CALCITE-2331] Evaluation of predicate "(A or B) and C" fails for Elasticsearch adapter (Andrei Sereda)
Add new PredicateAnalyzer which uses visitor pattern to construct correct
expression. The original version was copied from Dremio project.
Thanks to their team for improving calcite-ES integration.
Create internal QueryBuilders which mimics funtionality of original ES
API (TermQuery, BoolQuery, RangeQuery etc.) Unfortunately high-level
client (were query DSL is exposed) depends on elastic core. The latter
brings many dependencies (including netty, lucene etc.) and is compatible
only between major version. The goal of this adapter is to be
interoperable with any (most?) ES version(s).
Add separate tests for boolean logic.
