Redirect mcollective_facts_yaml_refresh cron to /dev/null

[hanej]

The mcollective_facts_yaml_refresh cron job is sending emails when the refresh_facts.rb job generates warnings on stderr. The 99% of the time the warnings are environment related and are intermittent so they can be safely ignored.

Pull request #207 opened for this.

Thank you @hanej releases should come in the next week or two

I apologize @ripienaar, the commit I sent you doesn't property redirect stderr. It should either be &>/dev/null or >/dev/null 2>&1. The current commit is backwards. How would you like me to resolve?

[ripienaar]

oh yeah I totally missed that doh

I reopened it - you can send another PR to fix it
