Added a python-backed class io.murano.system.MetadefBrowser providing
a read-only access to Glance Metadefinition Catalog. The class can
fetch namespaces mapped to a particular resource type and the contents
(objects) of a given namespace. Since the catalog is not updated
frequently the class provides caching capabilities for the fetched
data.
The MuranoPL part of the class provides a single method called
canBeAppliedTo which may be used to check whether some tag can be
applied to a particular type of resource.
Since Glance connectivity is required, a new configuration section is
added to provide capabilities to tune conection properties (url,
endpoint type, encryption etc).
