[FLINK-8200] RocksDBAsyncSnapshotTest should use temp fold instead of fold
with fixed name
Using fixed folder in test makes test fail when different users run the
test in the same machine. We should TemporaryFolder instead to avoid the
conflicts and make the test folder be cleared automaticlly when execution
finished.
