Add output validation for substitution mappings

1. The outputs defined by the topology template have to match the
attributes of the node type or the substituted node template,
2.The observable attributes of the substituted node template have to be
defined as attributes of the node type or outputs in the topology
template.

The patch will be submitted to openstack  too.
