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

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
