Extend UMA

AM exposes extension points that enable you to extend UMA services when built-in functionality does not fit your deployment.

AM provides a number of extension points for extending the UMA workflow that are provided as filters and that are dynamically loaded by using the Java ServiceLoader framework during the UMA workflow.

Resource registration extension point

Use the ResourceRegistrationFilter extension point to extend UMA resource registration functionality.

Resource registration extension methods

`beforeResourceRegistration`	resourceSet (type: `ResourceSetDescription`)	Invoked before a resource is registered in the backend. Changes made to the resourceSet object at this stage will be persisted.
`afterResourceRegistration`	resourceSet (type: `ResourceSetDescription`)	Invoked after a resource is registered in the backend. Changes made to the resourceSet object at this stage will not be persisted.

Permission request extension point
