This commit makes the barbican wsgi script consistent with other services by leveraging the pbr wsgi_scripts entrypoint to expose it. While you could still leverage the bundled app.wsgi the entrypoint barbican's behavior the same as other services. As part of this the app.wsgi script is deprecated and will be removed in the future.
