- remove old bucket policy handling - add new policy handling - add new policy handling unit tests This patch brings support to bucket policy to have more control not limiting to anonymous. Bucket owner controls to allow/deny any rest API. For example server side encryption can be controlled by allowing PUT/GET objects with encryptions including bucket owner.
