[WILL BE SPLIT UP] Start adjusting some modules

[felixfontein]

SUMMARY

Modules I want to adjust:

• docker_container_exec
• docker_container_info
• docker_container
• docker_host_info
• docker_image_info
• docker_image_load
• docker_image
• docker_login
• docker_network_info
• docker_network
• docker_prune
• docker_volume_info
• docker_volume

The idea is to support Python 2.7+. Maybe it also works with 2.6, but I don't know.

Ref: #364

The idea is not that this PR should convert all modules and plugins, but start with a few to see which helper APIs should be provided by APIClient and by AnsibleDockerClientBase.

[felixfontein]

docker_container is a lot harder to convert, so I'll work on that in a follow-up PR. I have been long thinking about a general rework of that module anyway, maybe I'll combine that with adjusting the module to use the vendored code.

[felixfontein]

I will probably split this up into one general PR (for the common module utils), and then once that's merged, one PR per module and plugin, so that it will be easier to review.

[felixfontein]

The module_utils and plugin_utils part is in #398.

[felixfontein]

I've rebased now that the separate vendoring PR has been merged.
