Add support for setting a container HostConfig when creating a container

[wallrj]

New! It is now possible to set a container's HostConfig when creating a container. Previously this was only available when starting a container.

See https://docs.docker.com/reference/api/docker_remote_api/#v115

So it would be useful if Client.create_container could accept all the HostConfig related parameters that are currently accepted by Client.start.

Meanwhile, we can construct a config dictionary and supply that to Client.create_container_from_config.

Also note:

New! Passing the container's HostConfig on start is now deprecated. You should set this when creating the container.

So there should probably be a deprecation warning when those parameters are supplied to start

But that's probably a separate issue.
