delete Resource
abstract fun deleteResource(qualifiedName: String, completion: () -> Unit, failureHandler: (ErrorCode, Throwable?) -> Unit)
Delete the ResourceType linked to the qualified name. If the ResourceType is a ResourceType.PACKAGE or a ResourceType.DIRECTORY, all of its children should be deleted as well. All deleted references should be removed from the reference tree.
If it is a ResourceType.REPRESENTATIVE, the package it represents should be deleted and handled as if the package were the target of deletion.
