Wrong s3_token filter configuration for swift-proxy for Juno

[Aleksandr Didenko]

I'm getting the following error when starting swift-proxy on Ubuntu deployed with puppet-swfit module v 4.1.0 (Juno packages)

Starting proxy-server...(/etc/swift/proxy-server.conf)
Traceback (most recent call last):

ImportError: No module named s3_token

A part of /etc/swift/proxy-server.conf config:

[filter:s3token]
paste.filter_factory = keystone.middleware.s3_token:filter_factory

It should be:

[filter:s3token]
paste.filter_factory = keystoneclient.middleware.s3_token:filter_factory

Because s3_token is a part of keystoneclient middleware since Juno:
https://github.com/openstack/python-keystoneclient/tree/master/keystoneclient/middleware

It should be fixed in this template:

    Since Juno s3_token middleware is a part of keystoneclient, not
    keystone.
