Major Description
Ranger policy model supports setting up policies with fine-grained permissions - like create/alter/drop/select/insert/update/truncate, read/write/list/create/delete/mkdir. Supporting policies to specify permissions as broad categories like CRUD, will make it easier for policy authors - especially for tag-based policies.
In addition, it will also help to have a built-in access-type that captures all other access-types - like ALL.
