This changes enables the Keystone v3 api. It can be toggled on and off via the preferred-api-version option. When services join the identity-service relation they will be presented with a new parameter api_version which is the maximum api version the keystone charm supports and matches what was set via preferred-api-version. If preferred-api-version is set to 3 then the charm will render a new policy.json which adds support for domains etc when keystone is checking authorisation. The new policy.json requires an admin domain to be created and specifies that a user is classed as an admin of the whole cloud if they have the admin role against that admin domain. The admin domain, called admin_domain, is created by the charm. The name of this domain is currently not user configurable. The role that enables a user to be classed as an admin is specified by the old charm option admin-role. The charm grants admin-role to the admin-user against the admin_domain. Switching a deployed cloud from preferred-api-version 2 to preferred-api-version 3 is supported. Switching from preferred-api-version 3 to preferred-api-version 2 should work from the charm point of view but may cause problems if there are duplicate users between domains or may have unintended consequences like escalating the privilege of some users so is not recommended.
