Section number and name: 9.8 Technology Previews - filesystems and storage

Describe the issue: The Jira https://issues.redhat.com/browse/RHEL-7936 covered the kernel portion of "NFS over TLS" feature.  In the discussion it was clear this feature also needed a userspace component (ktls-utils) which was not shipped in RHEL9.4 GA (it was subsequently shipped in a 9.4.z, see https://issues.redhat.com/browse/RHEL-16641) and this too is Technology Preview.

Suggestions for improvement:

Just add a small section stating that "NFS over TLS feature" is in a Technology Preview support status.

Additional information:

This was an oversight on the team due to multiple factors (the kernel developer left Red Hat, ktls-utils was not shipped in time, more testing was needed, etc).

We need to clarify our docs as soon as we can to make sure customers and sales and everyone is aware of the support status of NFS over TLS.  The plan of record is to transition NFS over TLS to fully supported in RHEL9.6 but this release is a ways off. 

There is a kbase that covers the support status and will be updated as needed:
