Block Storage API v2 StarlingX extensions

StarlingX extensions to the OpenStack Block Storage API such as backup status and export/import actions for volumes and snapshots.

The typical port used for the Block Storage REST API is 8776. However, proper technique would be to look up the cinderv2 service endpoint in keystone.
