Create automation for OSC/ondemand#1209

[johrstrom]

I added automation to create these tickets. Right now there's no distinction between ansible and puppet, just let me know if you want it to distinguish between the two.

I think this is fine, this is a valid change for the Puppet module. If something isn't I can just close out the issue.
