RFR: JDK-8199352: The Jib artifact resolver in test lib needs to print better error messages

The Jib artifact resolver is not very good at telling us why things go 
wrong. The reason is that it swallows exceptions. This patch changes the 
API from throwing a FileNotFoundException, which I don't really think 
fits correctly in all cases, to a new API specific exception.

I have greped for all uses of this API in the tests and changed the 
exception type caught at the caller location. I verified that I didn't 
break anything by compiling all the affected test classes and by running 
some of them for a bit.

With these changes it should be easier to diagnose problems with 
resolving artifacts in the future.
