Parameter Scheme

Create a well defined template parameter scheme that can be used to express special labels in template resource attributes that are used for supplying values upon instantiating entities using the template. In addition to a template parameter label, we also need a standard mechanism to specify values for the labels when using the API.

This feature can be used for supplying a unique name to an Application Assembly at the time it is created and started. This would allow multiple Application Assemblies to be created from the same template to run concurrently, and offer a way to easily tell them apart from each other. The scheme should be flexible such that it works for Component Templates as well, so that it can be used for passing in configuration parameters that are employed by a downstream configuration management system.
