Sean McGinnis a96fad9f3b Fix api-ref response code title levels 
Using the wrong character resulted in the wrong title level
being used for the response codes, which in turn caused the
"detail" show/hide toggle to not be able to hide all of the
per-endpoint details. This corrects these to be at the correct
level.

Also ran into issues after changing them where sphinx was not
happy with the random title levels. This appears to be due to
the order processed and whether not earlier included files had
all subsequent levels. Adding an additional title in our first
included file resolved that problem.

Volume snapshots (snapshots)
============================
A snapshot is a point-in-time copy of the data that a volume
contains.
When you create, list, or delete snapshots, these status values are
possible:
**Snapshot statuses**
+----------------+---------------------------------------------+
| Status | Description |
+----------------+---------------------------------------------+
| creating | The snapshot is being created. |
+----------------+---------------------------------------------+
| available | The snapshot is ready to use. |
+----------------+---------------------------------------------+
| backing-up | The snapshot is being backed up. |
+----------------+---------------------------------------------+
| deleting | The snapshot is being deleted. |
+----------------+---------------------------------------------+
| error | A snapshot creation error occurred. |
+----------------+---------------------------------------------+
| deleted | The snapshot has been deleted. |
+----------------+---------------------------------------------+
| unmanaging | The snapshot is being unmanaged. |
+----------------+---------------------------------------------+
| restoring | The snapshot is being restored to a volume. |
+----------------+---------------------------------------------+
| error_deleting | A snapshot deletion error occurred. |
+----------------+---------------------------------------------+
