Description:
When trying to extract information from a cluster configuration file with "ndb_config --config-file=..." warnings like "Running arbitrator on the same host as a database node" are printed to stdout, not stderr. There is no option to turn these warnings off or to redirect them so any tool parsing the output of ndb_config has to add extra parsing code to distinguish between warnings and actual results.

How to repeat:
$ ndb_config --config-file=config.ini --rows='\n' --query=hostname
Cluster configuration warning:
  arbitrator with id 62 and db node with id 1 on same host ndbsup-1
  arbitrator with id 63 and db node with id 2 on same host ndbsup-2
  Running arbitrator on the same host as a database node may
  cause complete cluster shutdown in case of host failure.
ndbsup-1
ndbsup-2
ndbsup-3
ndbsup-4
ndbsup-1
ndbsup-2

Suggested fix:
either print warnings to stderr instead of stdout or add a --quiet option
