The migration of the zookeeper-statsd image itself already happened as
it was our test case. That said I found a small typo that needs fixing
(and will clean up the extra image that was created later). We also
update zookeeper-statsd to pull the base python image from quay.io
The real fun happens with haproxy-statsd. We update the image to pull
the python base image from quay.io and set it up to publish to quay.io
itself.
