1. update Appraisals file with new chef versions

2. run 'appraisal' to generate the gemfiles for all the chef versions

3. run 'appraisal rake generate_chef_metdata' to generate the json for all the chef versions

4. run 'appraisal chef_12.1.1 rake generate_chef_metadata' to generate json for one chef version

The Rakefile is not intended to be run directly without invoking appraisal to essentially bundle
exec it against the correct gemfile.
