The 'stage' features are largely broken in the UI. We should update the BPMN to make it easier for the UI to display interesting information about the lifecycle stage. In particular, I think we need a Property set on the artifact to indicate the coarse-grained deployment stage. This can be used in queries and when displaying the list of deployments.
Verified in S-RAMP 6.0.0.ER1: * Walked through whole deployment process specified in SimpleReleaseProcess, application was successsfully deployed to all specified stages * Deployment stage is displayed in deployment details, more detailed ontolgy classifiers in s-ramp repository view * Deploying a new version of an application causes undeployment of older version
