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.
Do we want to mention support (or lack thereof) for Solarish (i.e. illumos based) distributions? Examples would be OmniOS, SmartOS and OpenIndiana. I think we could manage at least Tier 2 for these with the Solaris packages if full support isn't feasible.
