Previously in ansible the no_log: True attribute on a task or a play hides
any logging from hitting syslog on the remote system.
In addition to this, on 1.8, I’ve also implemented a much requested new
feature that also hides this from callbacks, such that the data as shown
by -v, or passed to any callback plugins, is censored.
Try it by adding no_log: True to any task.
(I’ve also added this to the FAQ documentation, which is not pushed just yet)
