Remove the Veritas HyperScale Driver
The Veritas HyperScale driver was marked unsupported in the Stein release. It hasn't reported on a patch in 327 days. This is outside Cinder's CI requirements and therefore the driver is being removed. Change-Id: I44a4dc52b2cced6dac98aa895aa3de1df0926fc5

upgrade:

- |
|

The Veritas HyperScale storage driver has been removed after completion of its
|
||||
deprecation period without a reliable 3rd Party CI system being
|
||||
supported. Customers using the Veritas HyperScale driver should not upgrade
|
||||
Cinder without first migrating all volumes from their Veritas backend
|
||||
to a supported storage backend. Failure to migrate volumes will
|
||||
result in no longer being able to access volumes backed by the Veritas
|
||||
HyperScale storage backend.
|
||||
other:
|
||||
- |
|
||||
The Veritas HyperScale storage driver was marked unsupported in Stein due to
|
||||
3rd Party CI not meeting Cinder's requirements. As a result the
|
||||
driver is removed starting from the Train release.
