ping @albers PTAL

It's really hard to keep up with all the changes in Docker. But I figured out how to work with this repo and found a hack that gets the completion script into the dev container. moby/moby#33801 is not present here.

I verified the changes successfully. All features are present. The script can be loaded with ancient bash version as well (MacOS).

One point though: The implementation of --detach in 25ac146 is suboptimal (not wrong, but not helpful). There is already an unmerged fix which should go here: docker/cli#284.

can we also pull in docker/cli#321 (was just merged)?

[andrewhsu]

I brought in docker/cli@e7e77b5 and rebased to 17.06 branch.
