VAST Data Volume Driver

This commit introduces the VAST Data driver for Cinder.

The VAST Data Platform unifies storage, database, and
containerized compute into a single, scalable software platform
to power AI and deep learning in modern data centers and clouds.
VAST Data's architecture is designed to deliver performance,
scalability, and simplicity, leveraging a disaggregated
shared-everything (DASE) design to enable the consolidation of
workloads on a single, highly efficient storage system.

The Cinder driver for VAST Data currently supports the
following functionality:

Create volume
Delete volume
Attach volume
Detach volume
Extend volume
Create snapshot
Delete snapshot
Create volume from snapshot
Create volume from volume (clone)
