    Replace local storage of domain UUIDs with leader storage

    Currently the Keystone leader charm creates new domains and stores
    the UUIDs locally on disk. This approach predates charm relation-/
    leader- storage, is error prone, and causes problems in HA setups.

    Move to leader storage and remove old interfaces. There is no need
    to migrate the on-disk stored data as it is read from the deployment
    and stored as a part of the upgrade process.

    Do not set default values for service_tenant_id, admin_domain_id and
    default_domain_id. This will cause context to be incomplete on peer
    units until the values are actually available.

    Change functional tests to run on Keystone cluster to verify contents of
    configuration and operation of services in clustered environment.
