Docker Networking Support

Commands for docker networking is now available. You can create, delete, inspect, discover, attach container, and detatch containers via the commands. The create also support all advanced parameters to e.g. set IPam options etc.

This aloso comes with an enhancement form @megafinz that allows you to wait for a container to properly shut down.

Networking services and fluent API will come in a later release, but the foundation is laid for docker networking using the commands.
