Simon Willnauer 30acba624d [TEST] Add a more restrictive thread leaks filter 
Today all threads are allowed to leak a suite. This is tricky since
it essentially allows resource leaks by default where for instance
test private TransportClients will never get closed and consume
resources influencing other tests. It also hides threads that
are not fully under elasticsearchs control like the Lucene
TimeLimitingCollector thread. This commit restricts the threads
that can leak a suite to the threads spawned from testclusters
and fixes sevearl places that leaked threads.

Closes #7833

@defaultMessage spawns threads with vague names; use a custom thread factory and name threads so that you can tell (by its name) which executor it is associated with

@defaultMessage Collections.sort dumps data into an array, sorts the array and reinserts data into the list, one should rather use Lucene's CollectionUtil sort methods which sort in place
