SOLR-17414: multiThreaded search: don't throw RejectedExecutionException (#2701)
When searching with multiThreaded=true, the internal tasks may now block
instead of enqueuing with a risk of rejection. Solr will use less resources
under stress but to get the most of your machine, you may want to increase the
thread pool.
And:
* Revert ExecutorUtil change from SOLR-17298
* Revert ExecutorUtil change from SOLR-13350
* rename CoreContainer.collectorManager to indexSearcherExecutor
(cherry picked from commit 7405bb19fa424ec79c6daaafd986670dc54d7dfe)

> Since the new multiThreaded search feature landed, I see a new test
> failure involving "RejectedExecutionException" being thrown
> [link|https://ge.apache.org/s/5ack462ji4mlu/tests/task/:solr:core:test/details/org.apache.solr.search.TestRealTimeGet/testStressGetRealtime?top-execution=1].
> It is thrown at a low level in Lucene building TermStates
> concurrently. I doubt the problem is specific to that test
> (TestRealTimeGet) but that test might induce more activity than most
> tests, thus crossing some thresholds like the queue size -- apparently
> 1000.
> *I don't think we should be throwing a RejectedExecutionException
> when running a Search query*
