* The static threadpool leaks a lot of memory in these tests because it prevents things like the connect listeners from `org.elasticsearch.transport.TcpTransport#initiateConnection` to be GCed between tests (since they keep being referenced by the threadpool) which in turn reference channels and their underlying buffers * I could not find any slowdown in executing these tests from this change, if anything they are slightly faster now on my machine * Relates #36906 (which may be caused by slowness from leaking memory and also becomes testable in a loop by this change)

* If the threadpool gets shut down before the testnodes we run into an error => fixed by moving to single `After` method * Relates #36976
