Remove NUMERIC_HASHING_THRESHOLD (#10313)
* Make NUMERIC_HASHING_THRESHOLD configurable

Change the default numeric hashing threshold to 1 and make it configurable.

Benchmarks attached to this PR show that binary searches are not more faster
than doing a set contains check. The attached flamegraph shows the amount of
time a query spent in the binary search. Given the benchmarks, we can expect
to see roughly a 2x speed up in this part of the query which works out to
~ a 10% faster query in this instance.

Join filter pre-analysis simplifications and sanity checks. (#10104)
* Join filter pre-analysis simplifications and sanity checks.

- At pre-analysis time, only compute pre-analysis for the innermost
  root query, since this is the one that will run on the join that involves
  the base datasource. Previously, pre-analyses were computed for multiple
  levels of the query, some of which were unnecessary.
- Remove JoinFilterPreAnalysisGroup and join query level gathering code,
  since they existed to support precomputation of multiple pre-analyses.
- Embed JoinFilterPreAnalysisKey into JoinFilterPreAnalysis and use it to
  sanity check at processing time that the correct pre-analysis was done.

Tangentially related changes:

- Remove prioritizeAndLaneQuery functionality from LocalQuerySegmentWalker.
  The computed priority and lanes were not being used.
- Add "getBaseQuery" method to DataSourceAnalysis to support identification
  of the proper subquery for filter pre-analysis.

* Fix compilation errors.

* Adjust tests.

Refactor JoinFilterAnalyzer - part 2 (#9929)
* Refactor JoinFilterAnalyzer

This patch attempts to make it easier to follow the join filter analysis code
with the hope of making it easier to add rewrite optimizations in the future.

To keep the patch small and easy to review, this is the first of at least 2
patches that are planned.

This patch adds a builder to the Pre-Analysis, so that it is easier to
instantiate the preAnalysis. It also moves some of the filter normalization
code out to Fitlers with associated tests.

* fix tests

* Refactor JoinFilterAnalyzer - part 2

This change introduces the following components:
 * RhsRewriteCandidates - a wrapper for a list of candidates and associated
     functions to operate on the set of candidates.
 * JoinableClauses - a wrapper for the list of JoinableClause that represent
     a join condition and the associated functions to operate on the clauses.
 * Equiconditions - a wrapper representing the equiconditions that are used
     in the join condition.

And associated test changes.

This refactoring surfaced 2 bugs:
 - Missing equals and hashcode implementation for RhsRewriteCandidate, thus
   allowing potential duplicates in the rhs rewrite candidates
 - Missing Filter#supportsRequiredColumnRewrite check in
   analyzeJoinFilterClause, which could result in UnsupportedOperationException
   being thrown by the filter

* fix compile error

* remove unused class

Broker: Add ability to inline subqueries. (#9533)
* Broker: Add ability to inline subqueries.

The main changes:

- ClientQuerySegmentWalker: Add ability to inline queries.
- Query: Add "getSubQueryId" and "withSubQueryId" methods.
- QueryMetrics: Add "subQueryId" dimension.
- ServerConfig: Add new "maxSubqueryRows" parameter, which is used by
  ClientQuerySegmentWalker to limit how many rows can be inlined per
  query.
- IndexedTableJoinMatcher: Allow creating keys on top of unknown types,
  by assuming they are strings. This is useful because not all types are
  known for fields in query results.
- InlineDataSource: Store RowSignature rather than component parts. Add
  more zealous "equals" and "hashCode" methods to ease testing.
- Moved QuerySegmentWalker test code from CalciteTests and
  SpecificSegmentsQueryWalker in druid-sql to QueryStackTests in
  druid-server. Use this to spin up a new ClientQuerySegmentWalkerTest.

* Adjustments from CI.

* Fix integration test.

Renamed 'Generic Column' -> 'Numeric Column'; Fixed a few resource leaks in processing; misc refinements (#5957)
This PR accumulates many refactorings and small improvements that I did while preparing the next change set of https://github.com/druid-io/druid/projects/2. I finally decided to make them a separate PR to minimize the volume of the main PR.

Some of the changes:
 - Renamed confusing "Generic Column" term to "Numeric Column" (what it actually implies) in many class names.
 - Generified `ComplexMetricExtractor`
