      Bug#12603874 - mtr.pl should dump cluster log files when ndbcluster_wait_started() fails
       - We have seen mystery cluster start failures and would like to improve our
      possibility to diagnose why the cluster processes has failed to start by
      dumping the cluster log files to stdout.
       - This is a huge improvement compared to before when only the message 'Start of
      mysql_cluster.X cluster failed'
