    Support properties_target when fetching namespaces
    
    This allows specifying a properties target when fetching metadata
    definitions namespaces from glance, and updates the instance
    metadata widget to show only "metadata" properties (as opposed to
    "scheduler_hints") when creating an instance or updating the
    metadata.

Title:
  Instance Metadata should only show metadata definitions with
  properties_target: metadata

Status in OpenStack Dashboard (Horizon):
  Fix Released

Bug description:
  The ability to add metadata to an instance leveraging these
  definitions at launch time was recently added to horizon. [0] It was
  also added as an action on the instances table [1].

   In a follow up discussion, somebody asked about using the metadata definitions to also choose nova scheduler hints at launch time and how to make sure that the two weren't confused. This raised our awareness that we don't have properties_target set to "metadata" (rather than "scheduler_hints") for OS::Nova::Instance on the following software namespace files:
  The metadata definitions the Glance Metadata Definitions catalog allow each namespace to be associated with a resource type in OpenStack. Some types of resources have more than one type of properties, so the namespaces allow this to be specified using a properties_target attribute.

  We have now updated the existing namespaces in Glance for
  OS::Nova::Instance to have a properties target  set to "metadata" [3].

  So, the NG launch instance metadata step and project update metadata action should be updated to only show namespaces that have have the properties_target of metadata set.

  Please note that there will be an additional bug opened on glance to
  change these namespaces from OS::Glance::Instance to OS::Nova::Server
  to align with the heat resource type.

  http://docs.openstack.org/developer/heat/template_guide/openstack.html#OS::Nova::Server

  ** It should be noted that updating namespaces is already possible
  with glance-manage. E.g.

  ttripp@ubuntu:/opt/stack/glance$ glance-manage db_load_metadefs etc/metadefs -h
  usage: glance-manage db_load_metadefs [-h]
                                        [path] [merge] [prefer_new] [overwrite]

  positional arguments:
    path
    merge
    prefer_new
    overwrite

  So, you just have to call:

  ttripp@ubuntu:/opt/stack/glance$ glance-manage db_load_metadefs
  etc/metadefs true true
