The swift-object-expirer is provided by the 'openstack-swift-proxy'
package and thus it is unavailable on swift-object image. This change
adds a new Docker image to fulfill this requirement and stop using
swift-object image in this case.
This image is needed while RDO does not fix the packaging. The issue
is being tracked in:
