@dwalluck Hi, it is a good time for you to review my changed.
I have introduced PNC 2.0 client and did some refactoring, when doing the migration with attempts to reduce code complexity and make the maintenance easier.

I followed these steps:

1. I studied the original code and tried to understand it
2. I reduced the complexity of the find method by removing unused data from PNC
3. I've added the new client and removed old
4. Rewrote the whole code without caching using the new client
5. Extracted the code to PncBuildFinder to reduce complexity and introduced BuildFinderUtils for the shared logic
6. Performed other refactoring to reduce complexity of the BuildFinder

What's missing?

1. I removed caching as the way it was implemented it caused very hardly readable code and also not good reusability of the caches with more instances of the BuildFinder. I'll introduce caching on the Client level, which should provide better performance gains with less complexity in the business logic
2. Add integration tests and test everything. I did not test the code yet as I did many changes and rewrote some parts several times, but I'd like to have a review from you first :-)

I hope it won't be too big shock for you and you will like it :-)

@dwalluck Both methods are used now.

It is kind of strange to initialize here, no? I guess the only alternative is to make them static? JUnit has a @BeforeClass but it must be a static method.

I think, it doesn't matter in this case as it is a test class, which should have only one instance anyway. I did it this way for some reason, which I cannot recall right now :-D
