docker.images.push does not throw an exception on authentication failures

[david0]

when calling images.push, I would expect an exception if the push fails for any reason. Instead a list of strings containing json(!) is returned.

In my case this was caused by using a credentials that were able to read the repository, but not to write on it.
I am using docker-py 7.1.0.

>>> d.images.push('registry.devops.company.de/sdm/devenv/docker/nds22:DMT')
