Chef::Resource.provides

Mark this resource as providing particular DSL.

Resources have an automatic DSL based on their resource_name, equivalent to
`provides :resource_name` (providing the resource on all OS's).  If you
declare a `provides` with the given resource_name, it *replaces* that
provides (so that you can provide your resource DSL only on certain OS's).
