Prior to this patch, run_once was basically ignored. This patch adds tracking on tasks that are tagged with run_once and will only allow it to be invoked once. This means if the run_once task fails, all the other hosts will continue to process their tasks like nothing happened. The play itself will exit if the run_once task fails at the end. For tripleo this means that run_once should not be used for any required tasks within a play but can be used to make sure a task will only run once time for a given play.
