             Summary: Update '/stacks' endpoint to use the api framework
                 Key: AMBARI-4277
                 URL: https://issues.apache.org/jira/browse/AMBARI-4277
             Project: Ambari
          Issue Type: Improvement
            Reporter: John Speidel
            Assignee: John Speidel


Part of the work being done to implement blueprints.
As a result of the blueprint work, the stacks api will be exposed to users and therefore needs to be updated to use the api framework to be consistent with the other api endpoints.

We currently have '/stacks' and '/stacks2' endpoints. The '/stacks' endpoint is very old and doesn't use the api framework and is inconsistent with the rest of the api. This endpoint isn't used by the UI or any other internal component and has never been documented. The 'stacks2' endpoint does use the api framework and is consistent with the other endpoints in it's usage except for the naming of the endpoint and some of it's children. This endpoint is currently used by the UI.

This task will basically clone the functionality of the 'stacks2' endpoint in the 'stacks' endpoint. The 'stacks' endpoint will be augmented with additional information in future tasks as needed by blueprints. Examples are component dependencies and topology tokens in config properties. After this work the 'stacks2' endpoint should basically be deprecated and the UI should eventually be phased over to the new 'stacks' endpoint.
