Subject: perf tests: Add daemon 'stop' command test

Add a test for the perf daemon 'stop' command. The test stops the daemon
and verifies all the configured sessions are properly terminated.

Committer testing:

  [root@five ~]# time perf test daemon
  76: daemon operations                                               : Ok
  [root@five ~]# time perf test -v daemon
  76: daemon operations                                               :
  --- start ---
  test child forked, pid 788560
  test daemon list
  test daemon reconfig
  test daemon stop
  test child finished with 0
  ---- end ----
  daemon operations: Ok
