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>

Filtering
The filtering flag (-f or --filter) format is of "key=value". If there is more
than one filter, then pass multiple flags (e.g., --filter "foo=bar" --filter "bif=baz")
The currently supported filters are:
- until (
<timestamp>) - only remove containers created before given timestamp
The until filter can be Unix timestamps, date formatted
timestamps, or Go duration strings (e.g. 10m, 1h30m) computed
relative to the daemon machine’s time. Supported formats for date
formatted time stamps include RFC3339Nano, RFC3339, 2006-01-02T15:04:05,
2006-01-02T15:04:05.999999999, 2006-01-02Z07:00, and 2006-01-02. The local
timezone on the daemon will be used if you do not provide either a Z or a
+-00:00 timezone offset at the end of the timestamp. When providing Unix
timestamps enter seconds[.nanoseconds], where seconds is the number of seconds
that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap
seconds (aka Unix epoch or Unix time), and the optional .nanoseconds field is a
fraction of a second no more than nine digits long.
