(possibly temporary) fix for #18519 Matches OpenSSH for non-tty sessions, where we don't actively terminate the process. Adds explicit tracking to the SSH server for these processes so that if we are shutting down we terminate them: this ensures that we can shut down quickly to allow shutdown scripts to run. It also ensures our tests don't leak system resources.
