Add volume prune --filter support
This change adds support for the `--filter` / `?filters` arguments on the `podman volume prune` subcommand. * Adds ParseFilterArgumentsIntoFilters helper for consistent Filter string slice handling * Adds `--filter` support to podman volume prune cli * Adds `?filters...` support to podman volume prune api * Updates apiv2 / e2e tests Closes #8672 Signed-off-by: Baron Lenardson <lenardson.baron@gmail.com>
