Michal Dulko 2e3299dc57 Widget to expose the metadata catalog from glance
In Juno, Glance is providing 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 both simple tags and key / value pairs
(properties, specs, etc).

This widget will get the metadata definitions from Glance
and will let the user add the metadata to the resource being edited.
It provides value validation as well as description information
about the metadata.

An implementation for Images is included in this patch. Additional
patches will be made for other resource types.

This patch also removes Edit Image Custom Properties screen as new
widget provides the same functionality. To avoid regressions owner
property is added to Image Detail screen.
