Issue XD-2705: Add ability to add Custom Metrics/Controllers To Admin Context 
See original report here https://github.com/spring-projects/spring-xd/issues/1300 "I've created a module with a custom Metric, Handler and Repository patterned after the AggregateCounter but then it appears that there doesn't seem to be a way to add anything to the Admin Context. The diagram at https://github.com/spring-projects/spring-xd/wiki/Extending-XD shows the Plugin Context as a sibling to the Admin Context which seems to verify my fears. It would be convenient to be able to add custom Metrics/Controllers/Repositories into the Admin Context so that they can be accessed through the same REST api as the other Metrics."
