[rdo-list] TripleO Network Template Generator

I sent this to openstack-dev too, but I think we have a number of users on rdo-list that might benefit from it too. Here's what I sent earlier: This is something that has existed for a while, but I had been hesitant to evangelize it until it was a little more proven. At this point I've used it to generate templates for a number of different environments, and it has worked well. I decided it was time to record another demo and throw it out there for the broader community to look at. See details on my blog: http://blog.nemebean.com/content/tripleo-network-isolation-template-gener... Most of what you need to know is either there or in the video itself. Let me know what you think. Thanks. -Ben
