Remove many uses of Thread.sleep() from streaming tests
This is a work-in-progress PR towards removing many of the `Thread.sleep()`
calls from Spark Streaming's test suite, since I think that these calls make
these tests race-prone and flaky.
I expect these test runs to fail, actually, since I uncovered some new bugs
in Streaming.
