This fix is a follow up for comment https://github.com/docker/docker/pull/28535#issuecomment-263215225 This fix provides `--filter until=<timestamp>` for `docker container/image prune`. This fix adds `--filter until=<timestamp>` to `docker container/image prune` so that it is possible to specify a timestamp and prune those containers/images that are earlier than the timestamp. Related docs has been updated Several integration tests have been added to cover changes. This fix fixes #28497. This fix is related to #28535. Signed-off-by: Yong Tang <yong.tang.github@outlook.com>
