Broke the chef-cookbook-prep builder into bundler and berkshelf steps because
both are not needed for every test. Renamed builders to reflect the underlying
tools used:
chef-cookbook-prep -> chef-bundler-prep
-> chef-berkshelf-prep
chef-cookbook-rspec -> chef-cookbook-chefspec
chef-cookbook-lint -> chef-cookbook-foodcritic
chef-cookbook-style -> chef-cookbook-rubocop
Enabled rubocop/style checks without gating for all cookbooks. Will add gating
once the Rubocop updates are in place and this is shown to work well.
