Configure ansible's stdout_callback to yaml for nicer output

For some reason, I see stdout_lines in output by foreman, while when running from command line, I see stdout_lines: <omitted>, which makes the output even nicer. Not sure if that's something related to my local setup. Anyway, I still think the output is much nicer than the default one.

LGTM, if no one objects, I'll merge :-) the output is definitely more readable

We use the same one in forklift. The only downside there is that commands that have colors show the literal escape codes. Not sure if here you'd have the same problem.

[iNecas]

We have support for color codes in foreman_ansible, so that should be fine

Thanks!

Thanks @iNecas, merging!

oh lol, github page didn't reload until I wrote a comment, then realized it's already merged, so thanks also @ekohl :-)
