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.
