MDEV-246 - Aborted_clients incremented during ordinary connection close
The problem was increment of aborted_threads variable due to thd->killed which was set when threadpool connection was terminated . The fix is not to set thd->killed anymore, there is no real reason for doing it..
Added a test that checks that status variable aborted_clients does not grow for ordinary disconnects, and that successful KILL increments this variable.
