Auto detection of Docker API version in docker and docker_image modules

Currently, these modules require docker-py>=0.3.0. But in version 1.1.0 docker-py gained option to auto detect API version [1].

I think Ansible can use it, if there is nothing that prevents to raise required version of docker-py
