[FLINK-3706] Fix YARN test instability
The most important change in this commit is that the `YarnTestBase.Runner`
doesn't do `try {} catch (Throwable t) { fail(t); }` anymore, which doesn't
lead to a test failure, because its called outside the main thread.
With the change, all throwables are reported back to the main thread and
fail the test there properly (many YARN tests benefit from this change).
@mxm could you quickly review the changes? The change is rather small, I
was considering to push a hotfix, but decided to do a quick PR review round.
