1. Avoid hanging forever after a parallel job was killed (#7834) …

   * Replace multiprocessing.pool with concurrent.futures.ProcessPoolExecutor to avoid deadlocks.
   
   In a multiprocessing.pool, if a process terminates in a non-clean fashion
   (for example, due to OOM or a segmentation fault), the pool will silently
   replace said process, but the work that the process was supposed to do
   will never be done, causing pylint to hang indefinitely.
   The concurrent.futures.ProcessPoolExecutor will raise a
   BrokenProcessPool exception in that case, avoiding the hang.
