Define a new resource type

You can associate a name to the ``my_nova.yaml`` template in an environment
file. If the name is already known by the Orchestration module then your new
resource will override the default one.

Making your template resource more "transparent"
================================================
If you wish to be able to return the ID of one of the inner resources
instead of the nested stack's identifier, you can add the special reserved
output "OS::stack_id" to your template resource.
.. code-block:: yaml
resources:
server:
type: OS::Nova::Server
outputs:
OS::stack_id:
value: {get_resource: server}
Now when you use "get_resource" from the outer template heat
will use the nova server id and not the template resource identifier.
