This PR proposes updates to the OCI runtime spec with z/OS platform-specific details, including adding namespaces, adding noNewPrivileges flag, and removing devices. These changes are currently in use by the IBM z/OS Container Platform (zOSCP) product - details can be found here: https://www.ibm.com/products/zos-container-platform.

Note: The "removing of devices" is not considered to be an incompatible change since no user would have been using the z/OS-specific portion of the runtime spec, prior to the initial zOSCP release.

Only glancing over; would it be clearer to move the removal of devices to a separate commit? Currently it made me almost consider that "namespaces" was a replacement for devices which was a bit confusing.

Or is it a replacement? 🙈

The ociVersion is the same as used in spec-example.json.

The deletion of devices and the addition of namespaces are unrelated. However, I thought that having these in a single PR would be more efficient, given this is the resultant of what is supported by z/OS Container Platform.
If this really needs to be split into separate PRs, we can do that also.
