It's no longer apparent that this is a glanceclient issue since it has
been fixed in the Glance Metadef Service. Closing as invalid until it
becomes apparent that this is a client issue as well.

** Changed in: python-glanceclient
       Status: In Progress => Invalid

Title:
  metadata definition property show should handle type specific prefix

Status in Glance:
  Fix Released
Status in Glance Client:
  Invalid

Bug description:
  metadata definition property show should handle type specific prefix

  The metadata definitions API supports listing namespaces by resource
  type.  For example, you can list only namespaces applicable to images
  by specifying OS::Glance::Image

  The API also support showing namespace properties for a specific
  resource type.  The API will automatically prepend any prefix specific
  to that resource type.  For example, in the
  OS::Compute::VirtCPUTopology namespace, the properties will come back
  with "hw_" prepended.

  However, if you then ask the API to show the property with the prefix,
  it will return a "not found" error.   To actually see the details of
  the property, you have to know the base property (without the prefix).
  It would be nice if the API would attempt to auto-resolve any
  automatically prefixed properties when showing a property.

  This is evident from the command line.  If you look at the below
  interactions, you will see the namespaces listed, then limited to a
  particular resource type, then the properties shown for the namespace,
  and then a failure to show the property using the automatically
  prepended prefix.

  * Apologize for formatting.
