Subject Re: Supporting cross-project Jenkins builds

I'd still go a bit further in the simplification of what testpatch does.

* patches must at root level (not even try to be smart)
* all testcases should always be run (else a change in hdfs could
affect yarn/tools but not be detected, or one in yarn affect tools)
