    Execute the keystone db setup earlier in the process

    As the keystone credential_migrate command can access
    the keystone database in cases the os_keystone role
    stopped prematurely, the db setup playbook is moved
    in front of the `keystone_credential_create.yml` playbook
    to prevent and race condition.
