Add `--filter until=<timestamp>` for `docker container/image prune`

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.

## 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 machines 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.
