Mark T. Voelker 931e2f8161 Create v3 API Reference
The Cinder v3 API was marked CURRENT in Mitaka, but there no API ref
was ever created.  This is problematic for end users and would hinder
the v3 API from being included in DefCore Interoperability Guidelines
somewhere down the line (since one of DefCore's Criteria[1] is that a
Capability be well documented).  This patch creates an API ref for v3.
It also adds a header to the v2 index to show that it is SUPPORTED,
whereas v3 is CURRENT.

=================
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.
