Fix for BUG##24415: Instance manager test im_daemon_life_cycle

Browse Source 
fails randomly.

The problem was that the test case used command line tool (mysql)
without specifying connect_timeout argument. In some cases,
this lead to hanging of the test case.

The fix is to specify --connect_timeout=1 when starting mysql.

Also, the patch contains polishing and various cleanups to simplify
analyzing of the problems further.

The patch affects only test suite, no server codebase has been
touched.


mysql-test/lib/mtr_im.pl:
  Remember PID of the IM-spawner -- a process, that is
  used to fork IM-angel.
mysql-test/lib/mtr_io.pl:
  Trim \n from the PID.
mysql-test/lib/mtr_process.pl:
  Don't complain if it was IM-spawner, who died.

  Update the result file.
mysql-test/r/im_life_cycle.result:
  Update the result file.

mysql-test/t/im_utils.imtest:
  Polishing: be more verbose.
mysql-test/t/kill_n_check.sh:

  if test case failed.
mysql-test/t/wait_for_process.sh:
  Log messages to the extrenal file so that they can be analyzed
  if test case failed.
mysql-test/t/wait_for_socket.sh:
