Fixed a couple linting issues with yamllint and ansible-review (#111)

- yamllint: "truthy value should be true or false"
   (Docs: https://github.com/adrienverge/yamllint/blob/master/yamllint/rules/truthy.py)
- ansible-review: "WARN: Best practice "Use YAML format for tasks and handlers rather than key=value" not met:"
  (Docs: 2aacd7462f/lib/ansiblereview/tasks.py)
