Fix for "AttributeError: 'list' object has no attribute 'keys'" error

[soar]

At this moment, when you call .tags() - you'll get error:

Traceback (most recent call last):
  File "test-docker.py", line 154, in <module>
    repo.tags()
  File "lib/dockerregistryclient/docker_registry_client/Repository.py", line 42, in tags
    return list(self._images.keys())
AttributeError: 'list' object has no attribute 'keys'

So self._images is list of dictionaries and has no keys() method.

Tested on python 3.5.2 and api_version=1.

I recently took over the maintenance of this project for my company and I'm a bit rusty on my python knowledge. What are the ramifications of these import statements? Will they break backward compatibility with older python versions?

@jkaldon the import won't break backwards compatibility, but it does provide forward compatibility.

Thank you!
