The trusts API uses new default policies that make it more
accessible to end users and administrators in a secure way. Please
consider these new defaults if your deployment overrides
trust policies.

[`bug 1818850 <https://bugs.launchpad.net/keystone/+bug/1818850>`_]
The trust policies have been deprecated. The ``identity:list_trusts``
policy now uses ``(role:reader and system_scope:all)`` instead of
``rule_admin_required``. The ``identity:list_roles_for_trust``,
``identity:get_role_for_trust``, and ``identity:get_trust`` policies now
use ``(role:reader and system_scope:all) or
user_id:%(target.trust.trustor_user_id)s or
user_id:%(target.trust.trustee_user_id)s`` instead
of``user_id:%(target.trust.trustor_user_id)s or
user_id:%(target.trust.trustee_user_id)s``. The ``identity:delete_trust``
policy now uses ``(role:admin and system_scope:all) or
user_id:%(target.trust.trustor_user_id)s`` instead of
``user_id:%(target.trust.trustor_user_id)s``. These new defaults
automatically account for system-scope and support a read-only role, making
it easier for system administrators to delegate subsets of responsibility
without compromising security. Please consider these new defaults if your
deployment overrides trust policies.
