wildfly-subsystem's ResourceDescriptor supports the ability to apply a transformer to all resource operations. The ability to apply a transformer to a specific operation is limited to the add resource operation currently.
This jira proposes to allow registration of a transformer for any specific operation, not just the add operation.
This is needed by the JGroups subsystem relies on ResourceDescriptor.getRuntimeResourceRegistration() from wildfly-clustering-common, intentionally omitted from wildfly-subsystem. In its place, we need a mechanism to transform the standard add and remove resource operations to in order to add additional OperationContext.Stage.MODEL steps.
