Port support for Simple 5.x HTTP Container to Jersey 2.0 (including all the tests).

I have ported Simple HTTP container support from Jersey 1.x to Jersey 2. This includes all the tests except one test (CanonicalizationFeatureTest) which I do not see a direct support in Jersey 2.0 yet. The other test EscapedURITest which is ignored since it fails with the current implementation for all containers. I have run the tests and they are all passing.
