Vendor in latest containers/storage and image
New progress bars.
Parallel Pulls and Pushes for major speed improvements
containers/image moved to a new progress-bar library to fix various
issues related to overlapping bars and redundant entries.
completions: Introduce transports completions
Allow storage-multiple-manifests
split up skopeo man pages
Add --quiet option to skopeo copy
completions: Fix bash completions when a option requires a argument
When copying images and the output is not a tty (e.g., when piping to a
file) print single lines instead of using progress bars. This avoids
long and hard to parse output.
