Apache SSL Support

[elliott-davis]

• This change adds a dependency on the ssl certificate cookbook.
• Updated apache2 cookbook dependency (fixes POODLE)
• If an SSL cert is not present, a self-signed cert will be generated.
• Apache will be configured to use both ssl and non-ssl for compatibility.
• Added integration tests (and fixed old one).
• Updated test kitchen rules to test SSL

I completely missed this PR when I started working out of another branch a few months ago, so I didn't pull it into the changes that were just published.

If you're able to resolve the merge conflicts, I can review it and look at merging it in more quickly.

Notes:

• There is a reference to wordpress::package in the default recipe, but I don't see a corresponding recipe.
• Using git on Linux distros sounds like a great idea. In the past I've had to add the git community cookbook as a dependency since it doesn't come on all stock images. I haven't had much time to dig into this to investigate.
