Dear whiskers. This PR[1] has been so long.
It is mainly to manage permission using annotations. An owner can configure permission for an entity in a Linux way (`rwxr-x`). The permission is only configurable for "owner" and "users". This PR started based on the idea to prevent an entity to be deleted by mistake. So in the small scope, it already meets the requirement though I am not quite sure it's reasonable to rely on annotations. Any feedbacks and opinions would be appreciated. Thank you. -dom [1] https://github.com/apache/openwhisk/pull/4058
