docker.images.list is console.log instead of returning Promise.

In some operations we need to send post requests to the Docker Engine API & It's currently not possible because Bridge.call only send GET request. We need to add POST request support too.

Instead of defining socket location in Dockernize initialization we can configure /var/run/docker.sock to be the default socket path.

so Dockernize will assign /var/run/docker.sock when initialize without socket path.

We need to implement a way to list containers. A new base node called containers with list as a sub node.

docker.containers.list()

Currently Bridge.call cannot handle query string. We need to send query string when creating containers to add name etc.

We need to implement a way to start containers.

docker.containers.start()

We need to implement a way to stop containers.

docker.containers.stop()
