Auto-enable Local HTTP Caching in Test Kitchen

Note: total experiment and hack, looks nasty, could be awesome:

Setup

• Drop the kitchen.local.yml into $HOME/.kitchen/config.yml
• Install polipo (with Mac: brew install polipo, with Ubuntu: apt-get install polipo)
• Drop polipo-start and polipo-console somewhere useful (perhaps $HOME/bin?)

# I'm sure this can all be replaced with a one liner, buried deep in chef somewhere.

Parallelization in Chef Recipes

Chef presently runs the resources in a recipe serially, one after the next. In this proposal, user-selected groups of resources will run their actions in parallel.

MVP (Minimum Viable Product) Features

 * BEWARE:
 * This file uses the Option key as a meta key.  This has the side-effect

If you want to check whether a node run_list includes a specific role (upon expansion), then you could use role? method on the Node object:

node.role?('name')

Alternatively, you can see whether either would work for you:

node.roles.include?('name')

node.run_list?('role[name]')
