remove ListenableFutures and revert to using the Guava implementation (#9944)
This change removes ListenableFutures.transformAsync in favor of the
existing Guava Futures.transform implementation. Our own implementation
had a bug which did not fail the future if the applied function threw an
exception, resulting in the future never completing.

An attempt was made to fix this bug, however when running againts Guava's own
tests, our version failed another half dozen tests, so it was decided to not
continue down that path and scrap our own implementation.

Explanation for how was this bug manifested itself:

An exception thrown in BaseAppenderatorDriver.publishInBackground when
invoked via transformAsync in StreamAppenderatorDriver.publish will
cause the resulting future to never complete.

This explains why when encountering https://github.com/apache/druid/issues/9845
the task will never complete, forever waiting for the publishFuture to
register the handoff. As a result, the corresponding "Error while
publishing segments ..." message only gets logged once the index task
times out and is forcefully shutdown when the future is force-cancelled
by the executor.

intelliJ inspections cleanup (#9260)
* intelliJ inspections cleanup

- remove redundant escapes
- performance warnings
- access static member via instance reference

The valuable changes in this delta are:
- using StringBuilder instead of string addition in a loop
    indexing-hadoop/.../Utils.java
    processing/.../ByteBufferMinMaxOffsetHeap.java
- Use class variables instead of static variables for parameterized test
    processing/src/.../ScanQueryLimitRowIteratorTest.java

Use DataSourceAnalysis throughout the query stack. (#9239)
Builds on #9235, using the datasource analysis functionality to replace various ad-hoc
approaches. The most interesting changes are in ClientQuerySegmentWalker (brokers),
ServerManager (historicals), and SinkQuerySegmentWalker (indexing tasks).

Other changes related to improving how we analyze queries:

1) Changes TimelineServerView to return an Optional timeline, which I thought made
   the analysis changes cleaner to implement.
2) Added QueryToolChest#canPerformSubquery, which is now used by query entry points to
   determine whether it is safe to pass a subquery dataSource to the query toolchest.
   Fixes an issue introduced in #5471 where subqueries under non-groupBy-typed queries
   were silently ignored, since neither the query entry point nor the toolchest did
   anything special with them.
3) Removes the QueryPlus.withQuerySegmentSpec method, which was mostly being used in
   error-prone ways (ignoring any potential subqueries, and not verifying that the
   underlying data source is actually a table). Replaces with a new function,
   Queries.withSpecificSegments, that includes sanity checks.

Add join-related DataSource types, and analysis functionality. (#9235)
* Add join-related DataSource types, and analysis functionality.

Builds on #9111 and implements the datasource analysis mentioned in #8728. Still can't
handle join datasources, but we're a step closer.

Join-related DataSource types:

1) Add "join", "lookup", and "inline" datasources.
2) Add "getChildren" and "withChildren" methods to DataSource, which will be used
   in the future for query rewriting (e.g. inlining of subqueries).

DataSource analysis functionality:

1) Add DataSourceAnalysis class, which breaks down datasources into three components:
   outer queries, a base datasource (left-most of the highest level left-leaning join
   tree), and other joined-in leaf datasources (the right-hand branches of the
   left-leaning join tree).
2) Add "isConcrete", "isGlobal", and "isCacheable" methods to DataSource in order to
   support analysis.

Other notes:

1) Renamed DataSource#getNames to DataSource#getTableNames, which I think is clearer.
   Also, made it a Set, so implementations don't need to worry about duplicates.
2) The addition of "isCacheable" should work around #8713, since UnionDataSource now
   returns false for cacheability.

* Remove javadoc comment.
