libpod: do not call (*container).Config()
Access the container's config field directly inside of libpod instead of calling `Config()` which in turn creates expensive JSON deep copies. Accessing the field directly drops memory consumption of a simple `podman run --rm busybox true` from 1245kB to 410kB. [NO TESTS NEEDED] Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
