Overview
Upgrade Pure cinder driver to use REST 2.x calls, rather than the historic (and function-limited REST 1.x).

This is partner driver request to backport and update their cinder-specific driver to the  Epoxy version.  This is driver-only code, not core Cinder changes. 

Goals / Acceptance Criteria 

• Backport the driver and deliver in the RHOS-18 
• Pass downstream regression CI tests for Cinder

Use Cases

• Updated Pure Cinder driver with OpenStack

Out of Scope

• No RH testing needed other than Cinder automation
• Other patches beyond the scope of this change set.

Documentation Considerations

No RH customer docs

Questions to Answer

• None{}

Business justification
Upgrading ot the Epoxy driver adds numerous bugfixes and features, but specifically allows customers wanting to migrate from VMware to OpenStack to perform the cinde rmanage command again a Pure Storage based VMware vVol directly into OpenStack with zero conversion requirements.
We will also be backporting a number of feature enhancements to support RansomWare detection and support for NVMe-TCP VLANs, correct backend QoS setting and enhanced schedule reporting characteristics
