Podman pod create --share-parent vs --share=cgroup
separated cgroupNS sharing from setting the pod as the cgroup parent, made a new flag --share-parent which sets the pod as the cgroup parent for all containers entering the pod remove cgroup from the default kernel namespaces since we want the same default behavior as before which is just the cgroup parent. resolves #12765 Signed-off-by: cdoern <cdoern@redhat.com> Signed-off-by: cdoern <cbdoer23@g.holycross.edu> Signed-off-by: cdoern <cdoern@redhat.com>

+#### **--share-parent**

+This boolean determines whether or not all containers entering the pod will use the pod as their cgroup parent. The default value of this flag is true. If you are looking to share the cgroup namespace rather than a cgroup parent in a pod, use **--share**

+Note: This options conflict with **--share=cgroup** since that would set the pod as the cgroup parent but enter the container into the same cgroupNS as the infra container.
