Commit 4116941c082be5d6e3addfe3f6b6d2ea468416e4 in kudu's branch

KUDU-3591 Fix the flaky test FsManagerTestBase.TestAddRemoveDataDirsFuzz
Reduce the failure rate of the test by lowering its loop
times. For example, when FLAGS_block_manager == "logr",
opens a data directory will open a RocksDB instance, it
consumes more time than that if FLAGS_block_manager == "log".

> The fuzz test scenario FsManagerTestBase.TestAddRemoveDataDirsFuzz from time
> to time fails when run with the RocksDB option. I'm not sure whether the
> failure is just due to very long runtime, or something has stuck -- that's to
> be triaged. Below are a few lines from the log: they came just before the
> dump of the threads' stacks. The test was declared as failed because of
> exceeding the maximum unit test's run time. The full log is attached.
