Looks quite good now.
If I can ask you for one more followup: To have faster tests, it would be
good to add the streaming distributed cache test and the batch distributed
cache test to the same file.
Can you change the `DistributedCacheTest` to extend
`StreamingMultipleProgramsTestBase` and put your test in there as well? That
will cause only one distributed mini cluster to be spawned, which typically
saves 1-2 secs in tests. May not seem much, but it adds up over the 1000s of
tests Flink has by now...
