Adds version 1.33 of the REST API, which exposes the ``storage_interface``
field of the node resource. This version also exposes
``default_storage_interface`` and ``enable_storage_interfaces`` fields
of the driver resource.
There are 2 available storage interfaces:
* ``noop``: This interface provides nothing regarding storage.
* ``cinder``: This interface enables a node to attach and detach volumes
by leveraging cinder API.
A storage interface can be set when creating or updating a node. Enabled
storage interfaces are defined via the
``[DEFAULT]/enabled_storage_interfaces`` configuration option. A default
interface for a created node can be specified with
``[DEFAULT]/default_storage_interface`` configuration option.
