# Summary:
#   Run remote command_list on all of the specified kubernetes clusters: controllers, etcd, or workers.
#
# Why:
#   We have kubernetes and want to run CM jobs / commands on the kube nodes, but CoreOS doesnt have python etc. on it so we can't use CM tools here unless we hack 'em up (which shouldn't), so shell always works.
#   Plan to continue to build tools on this and we can take output of this script and slurp up into database, feed to graylog, etc.
