[RFC PATCH 01/10] Add helper to report unsupported protocol features

[Chuck Lever <cel@kernel.org>]

From: Chuck Lever <chuck.lever@oracle.com>

In some cases, specifications permit a server to not implement
a feature (or part of a feature) being tested. That should not
count as a test failure. The helper added here can be used to
indicate that the test did not pass or fail, but that the server
under test does not support the tested feature.
