Alan Bishop f91aec5869 Add encryption_key_id to volume and backup details
Add microversion 3.64 for including the encryption_key_id in the
volume and backup details when the associated volume is encrypted.
This facilitates associating encryption keys (typically stored in
Barbican) with the volume or backup that uses it.

The encryption_key_id is included in the details only when the
associated volume is encrypted, and it isn't using the all-zeros
key ID used by the legacy fixed-key ConfKeyMgr.

Backups (backups)
=================
A backup is a full copy of a volume stored in an external service.
The service can be configured. The only supported service is Object
Storage. A backup can subsequently be restored from the external
service to either the same volume that the backup was originally
taken from or to a new volume.
When you create, list, or delete backups, these status values are
possible:
**Backup statuses**
+-----------------+---------------------------------------------+
| Status | Description |
+-----------------+---------------------------------------------+
| creating | The backup is being created. |
+-----------------+---------------------------------------------+
| available | The backup is ready to restore to a volume. |
+-----------------+---------------------------------------------+
| deleting | The backup is being deleted. |
+-----------------+---------------------------------------------+
| error | A backup error occurred. |
+-----------------+---------------------------------------------+
| restoring | The backup is being restored to a volume. |
+-----------------+---------------------------------------------+
| error_deleting | An error occurred while deleting the backup.|
+-----------------+---------------------------------------------+
If an error occurs, you can find more information about the error
in the ``fail_reason`` field for the backup.
List backups with detail
~~~~~~~~~~~~~~~~~~~~~~~~
.. rest_method:: GET /v3/{project_id}/backups/detail
Lists Block Storage backups, with details, to which the project has access,
since v3.31 if non-admin users specify invalid filters in the url,
API will return bad request.

Restore a backup
~~~~~~~~~~~~~~~~
.. rest_method:: POST /v3/{project_id}/backups/{backup_id}/restore
Restores a Block Storage backup to an existing or new Block Storage volume.
The name parameter will work only if a new volume is created.
If UUID is specified, the backup will be restored to the specified volume.
The specified volume has the following requirements:
* the specified volume status is ``available``.
* the size of specified volume must be equal to or greater than the size of
backup.
If no existing volume UUID is provided, the backup will be restored to a
new volume matching the size and name of the originally backed up volume.
In this case, if the name parameter is provided, it will be used as the
name of the new volume.
