Background

As of today, the docs describe how to set up a ServiceTemplateChain and use it in a ClusterDeployment. Additionally, the docs call attention to the detail that a ServiceTemplateChain is immutable, and thus cannot be revised to add to the list of SupportedTemplates, or to update the availableUpgrades. As a result, the ClusterDeployment that references this ServiceTemplateChain appears to be out of upgrade options, once a new version of the same ServiceTemplate becomes available.

There should be a documented recommended process that illustrates how to update the ClusterDeployment to a newer version of the ServiceTemplate in a way that still embraces the design goals of the ServiceTemplateChain.
