Ensure all errors thrown by image providers can be caught by developers. (#25980)
* Ensure all errors thrown by image providers can be caught by developers.

Add an `onError` parameter to the ImageCache.putIfAbsent method.
In the event that an error is thrown when resolving an image, catch if
this parameter is provided. Use the onError parameter to ensure that all
errors thrown are forwarded to the ImageStream error channel instead of
directly into the void.
