Sean McGinnis f3afb7b4fd api-ref: Add backup import and export 
During the migration to in-tree api-ref docs we somehow lost the details
for backup export_record and import_record. Adding back in.

Also fixing up a few records that referred to the wrong parameter record
names, resulting in their descriptions referring to volume transfer for
backup operations.

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. Backup and restore operations can
only be carried out on volumes that are in an unattached and
available state.
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_restoring | A backup restoration error occurred. |
+-----------------+---------------------------------------------+
If an error occurs, you can find more information about the error
in the ``fail_reason`` field for the backup.
