Snapshot manage extension (manageable_snapshots)
================================================

Creates or lists snapshots by using existing storage instead of allocating new
storage.


Manage an existing snapshot
~~~~~~~~~~~~~~~~~~~~~~~~~~~

.. rest_method::  POST /v3/{project_id}/manageable_snapshots

Creates a snapshot by using existing storage rather than allocating new storage.

The caller must specify a reference to an existing storage volume
in the ref parameter in the request. Although each storage driver
might interpret this reference differently, the driver should
accept a reference structure that contains either a source-id
or source-name element, if possible.

The API chooses the size of the snapshot by rounding up the size of
the existing snapshot to the next gibibyte (GiB).
