Changes to the backend Heat generator to process the parameters from the TOSCA input section, which would be passed in from the CLI or accept the default value. Thi also handles the similar get_attribute function in the output section. Add handler for the nodejs type, needed for the monitoring use case. Fix the test_blockstorage unit test to match the new expected generator output, due to a change in the Heat Nova server resource type. Change-Id: Id73aba9ebaa6828c676a7a2afdee7ec6ef2579d3
