Initial strawman for the 1.8.1 release notes

Would also be OK with dropping this, and simply publishing the blog as a separate item. Whilst I fully agree that POODLE is not related to 1.8.1 specifically, this _is_ the first release of jclouds after POODLE, so I think it's legitimate to at least reference it. We don't have anything to hide here, in my opinion.
