Initial branch

@thbishop can you please look at what I have so far as a replacement for the cfn_ohai_plugin?  I want to be sure I am inline with what your had envisioned.

I did make a change to the LC intut_metadata recipe to how it calls this cookbook. https://github.com/live-community/live_community_chef_repo/pull/297/files#L4L35 The only question there is if you want me to keep the `include_recipe 'cfn_metadata'` even though it isn't needed just for clarity.

The changes I know that are still needed are:
1. Write spec
2. set the default attribute values to null and put them in a wrapper (unless you think its okay as-is)
3. update the readme and change log
