Updated Ansible role to support final release of Jenkins 2. Secure out of the box!

[Karl Davis]

Howdy all,

Now that the final 2.0 (and 2.1, even) release is out the door, I've updated my Ansible role for installing Jenkins to move away from the .deb-based install and use the official APT repo: https://github.com/karlmdavis/ansible-jenkins2.

Additionally, I put together a (horrifyingly, and probably overly, complex) init.d script that enables this role to work securely even if you're customizing your Jenkins authentication/security realm. I've tested it using the GitHub OAuth plugin, and it seems to be working just fine.

Oh, and also:

• It's now idempotent-- it only reports changes when something actually changed.
  
• It will automatically update any/all Jenkins plugins with updates available.

Happy DevOpsing!
