Comment 0 for bug 1536430

the help commands about "md-namespace" and "md-resource-type-associate" don't work now.

such as:
$ glance help md-namespace-create

usage: glance md-namespace-create <NAMESPACE> <unavailable>

Create a new metadata definitions namespace.

Positional arguments:
  <NAMESPACE> Name of the namespace.
  <unavailable> Please run with connection parameters set to retrieve the
                 schema for generating help for this command

we will get a <unavailable> message. The reason is that the schema files doesn't work.
See https://bugs.launchpad.net/python-glanceclient/+bug/1481729 to get more detail.

That bug fixed image schema, but the namespace and resource_type still have the problem.
