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.
