Base Glance Metadata Definitions Admin UI
Provide a base admin UI for viewing, importing, and associating the
metadata definitions that can be used with various resource types
such as flavors, images, and host aggregates.
In Juno, Glance provided a metadata definitions catalog[1][2] where
users can register the available metadata definitions that can be used
on different types of resources (images, artifacts, volumes, flavors,
aggregates, etc). This includes key / value pairs such as
properties, extra specs, etc. Horizon landed several patches that
read these properties. You can view the functionality in the
"update metadata" action on Flavors, Images, and Host Aggregates.
This specific patch is to bring in the Admin UI for the basic coarse
grained actions on the definitions in the catalog. This includes creating
(importing) a namespace, viewing the overview details about
it, deleting the namespace, and associating the namespace for use with
specific resource types.
Future blueprints will be registered for:
- CRUD on individual metadata definitions within the namespace
For example, editing the default value of an individual property.

"""Returns an Image object populated with metadata for image
|
Fixes LP Bug#862664 - Improper calls to get_image
The glance.client.Client.get_image() call returns a
tuple of (metadata, image_iterator). Unfortunately,
Horizon's glance API calls get_image() when it means
to call get_image_meta(). Because the call to get_image()
simply ignores the image iterator returned from get_image(),
when the image iterator is garbage-collected, this causes
the connection to Glance to be closed, however by that time
the socket bound to the iterator has been switched out by
eventlet. The result is lots of these in the Glance API log:
2011-09-28 17:46:12 DEBUG [glance.store.filesystem] Found image at /opt/stack/glance/images/3. Returning in ChunkedFile.

This patch fixes the improper calls to get_image() by replacing them
with appropriate calls to get_image_meta().

Base Glance Metadata Definitions Admin UI
Provide a base admin UI for viewing, importing, and associating the
metadata definitions that can be used with various resource types
such as flavors, images, and host aggregates.
In Juno, Glance provided a metadata definitions catalog[1][2] where
users can register the available metadata definitions that can be used
on different types of resources (images, artifacts, volumes, flavors,
aggregates, etc). This includes key / value pairs such as
properties, extra specs, etc. Horizon landed several patches that
read these properties. You can view the functionality in the
"update metadata" action on Flavors, Images, and Host Aggregates.
This specific patch is to bring in the Admin UI for the basic coarse
grained actions on the definitions in the catalog. This includes creating
(importing) a namespace, viewing the overview details about
it, deleting the namespace, and associating the namespace for use with
specific resource types.
Future blueprints will be registered for:
- CRUD on individual metadata definitions within the namespace
For example, editing the default value of an individual property.

The typical pattern of limit and marker is to make an

initial limited request and then to use the last

namespace from the response as the marker parameter

is namespace. The way base namespaces are loaded into glance

typically at first deployment is done in a single transaction
