Platform support policy proposal

There is a fair amount of confusion about the specific operating system platforms, platform versions, etc. that Chef Software, Inc. supports for its products. This RFC will clarify this by calling out the individual operating systems and their releases as explicitly supported or not.
The ChefDK is a superset of the chef-client, though, so the chef-client builds will support client skus of windows.  You'll get that essentially for free, even if you don't bother testing the actual chef msi on a client sku, we know that it has to work.  Seems silly to take it out of the downloads page or intentionally cripple the installer.
