compat_resource cookbook

This cookbook brings the custom resource syntax from Chef 12.5 down to earlier versions (12.0-12.5).

This cookbook is early days. It has some travis tests verifying the test matrix of rubies and chef versions.

Usage

To use this cookbook, put depends 'compat_resource' in the metadata.rb of your cookbook. Once this is done, you can use all the new custom resource features to define resources. It Just Works.

For example, if you create resources/myresource.rb, myresource can use property, load_current_value and action (no need to create a provider). If you want to create Resource classes directly, extend from ChefCompat::Resource instead of Chef::Resource. Properties, current value loading, converge_if_changed, and resource_name will all function the same across versions.
