An RFC to standarize on two workflows

This RFC proposes two workflows as "supported", and abstracts
as much of their differences as possible through the use of
additional generators and functionality in the 'chef' command.

If accepted, this RFC would also serve as a guide for tool makers,
as to what the requirements are for maximum converage in the Chef
community.

While other workflows are possible, this RFCs job is to say which
ones we support officially.
Our intent is that there is a standard way to package up your assets for use with solo/zero as a first class part of the workflows that are supported (any workflow that doesn't work for those modes isn't supported, natch)
