This change was missed in pull/8689. Now that volume pruneing supports filters system pruneing can pass its filters down to the volume pruneing. Additionally this change adds tests for the following components * podman system prune subcommand with `--volumes` & `--filter` options * apiv2 api tests for `/system/` and `/libpod/system` endpoints Relates to #8453, #8672 Signed-off-by: Baron Lenardson <lenardson.baron@gmail.com>
