Setup a reasonable default for pids-limit 4096
CRI-O defaults to 1024 for the maximum pids in a container. Podman should have a similar limit. Once we have a containers.conf, we can set the limit in this file, and have it easily customizable. Currently the documentation says that -1 sets pids-limit=max, but -1 fails. This patch allows -1, but also indicates that 0 also sets the max pids limit.
