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.
Releng plans to have a tester for every platform we claim to support for Tier 1. This is our aspiration and ensures our gut feelings about Tier 1 support are actualities.
