Michele Baldessari 6b827c199b Support default pid limits in containers.conf
Starting With podman 2.X the default pids-limits has been halved from
4096 to 2048:
$ rpm -q podman && podman run --rm -it --net=host --name 'pids' edecd409281d sh -c 'cat /sys/fs/cgroup/pids/pids.max'
podman-2.2.1-3.module+el8.3.1+9392+c5f6d096.x86_64
2048

With podman-1.6.4 the global default pid-limits was hardcoded to 4096
and we had no way to tweak it.

With podman 2.X it is possible to override this in
/etc/containers/containers.conf with the pids_limit setting inside
[containers] in the /etc/containers/containers.conf ini-file:
$ cat /etc/containers/containers.conf
[containers]
pids_limit=6666

$ podman run --rm -it --net=host --name 'pids' edecd409281d sh -c 'cat /sys/fs/cgroup/pids/pids.max'
6666

By adding this we keep the older 4096 default so we do not regress and
at the same time we allow an operator to override this globally.
