Subject: [PATCH] Cinder matrix - Removal of Snapshot Attachment

This functionality is exposed via rpcapi (as a cinder backup
enhancement) and not the OpenStack Block Storage API. As such
it should be removed from the cinder support matrix.

Closes-Bug: #1934168
Change-Id: Icaca68a1be8151f4aa0c5a0a6baeb762492bd159

+    The optional driver feature "Snapshot Attachment" has been removed
+    from the `Cinder Driver Support Matrix
+    <https://docs.openstack.org/cinder/latest/reference/support-matrix.html>`_.
+    It is an enhancment used for backups, it is not exposed via the

+    misleading.
