Mark Veritas HyperScale Driver Unsupported

The Veritas HyperScale Driver 3rd Pary CI hasn't
reported in 153 days.  This does not meet the requirements
for Cinder's 3rd Party CI requirements.

As a result the driver is being marked unsupported in the
Stein release and should be removed in the 'T' release if
the problems are not resolved.
