blog post on using heat to install deis on rackspace cloud.

I'm not completely sure I'm doing this right,  but the contributions instructions seem to be somewhat out of date and the build/testing scripts bombed big time for me.

feel free to edit/cleanup/etc.
was doing some testing and found myself destroying and recreating DEIS environments dozens of times, as well as making errors during some of the steps. The rework made it a frustrating experience.
