Python fixes

[jan-cerny]

During my transformation to Python 3, I have found some minor problems, but they affect both Python 2 and Python 3, not only Python 3.

They are:

• Class docker.Client was renamed to docker.APIClient in python-docker-py 2.0.0.
• We had an anomalous backslash in a string which turned out to be fixed by it should be raw string instead.
• We haven't risen a correct NotImplementedError exception.
