Add bash completion for manifest lists and manifests

This completion is a simplification:

- There is no command to retrieve manifest lists.
  They appear among the images after being pushed and pulled back.
  The completion lists all images.

- The list returned by `docker images` also contains manifest lists.
  As we cannot filter these out, we again complete all images.
