Motivation
When a template resource which is disabled by a condition references another resource that's disabled by a condition, the CFn engine currently incorrectly raises a
ValidationErrorin the transformer, validator and executor. This is not in parity with AWS. See thereferences_to_conditions.ymltemplate for an example.Changes
visit_node_resources/visit_node_outputsentirely in the preproc so we don't even evaluate the resource block during template preprocessing time
