This fix tries to address the issue raised in 29999 where it was not possible to mask these items (like important non-removable stuff) from `docker system prune`. This fix adds `label` and `label!` field for `--filter` in `system prune`, so that it is possible to selectively prune items like: ``` $ docker container prune --filter label=foo $ docker container prune --filter label!=bar ``` Additional unit tests and integration tests have been added. This fix fixes 29999. Signed-off-by: Yong Tang <yong.tang.github@outlook.com>
