# NOTE(johngarbutt) The base rules here affect so many APIs the list
# of related API operations has not been populated. It would be
# crazy hard to manually maintain such a list.
# NOTE(gmann): Keystone already support implied roles means assignment
# of one role implies the assignment of another. New defaults roles
# `reader`, `member` also has been added in bootstrap. If the bootstrap
# process is re-run, and a `reader`, `member`, or `admin` role already
# exists, a role implication chain will be created: `admin` implies
# `member` implies `reader`.
# For example: If we give access to 'reader' it means the 'admin' and
# 'member' also get access.
