Upgrade/Update rubocop

Now that almost all of the rubocop blueprints have been completed, make
one final pass through all of the cookbooks ensuring they're all in
sync with each other.

- Upgrade rubocop to 0.18.1
- Fix violations caused by 0.18.1 upgrade
- Move Excludes for non-existent folders to Includes so they
  automatically cover future additions

Change-Id: Id66903d1ca0f5fc0fa3323cca2ec6880730db3fe
Implements: blueprint lint-and-unit-testing-for-havana
