Create and initialize new delegate.

We usually have this functionality in a builder somewhere else (like a Pipeline.Builder), but
we put it here for now for simplicity. Since this is container-only class, we will be able to
move this logic somewhere else at a later time without difficulties.

@param stageLib Stage library task instance.
@param configuration SDC Configuration
@param stageLibraryName Name of the stage library from which the delegator should be loaded.
@param exportedInterface Interface describing which delegator is needed
@param <R>  Interface describing which delegator is needed
@return Wrapped new instance of the delegator or null on any issue
