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.
I don't.  Ideally I'd say we support Gentoo and Arch.  And this'll probably become a bigger issue as ChefDK gets rolled out.  The fact that we've got folks building omnibus-chef installs with random dev headers and showing up in our issues when the health_check fails suggests to me that we look at disabling the health_checks for those platforms because strict-omnibus makes less sense there, or that we go ahead and start making and releasing official ominbus packages for them.
