> ZooKeeperUtils have a throws exception clause without throwing exceptions

>
> Flink's {{ZooKeeperUtils}} contains functions which have a throws clause even
> though they don't throw an {{Exception}}. This is wrong and should be fixed
> by removing the throw clauses.
> Changing the ZooKeeperUtils will help to properly implement the
> {{HighAvailabilityServices}} in the flip-6 branch, because the high
> availability service methods don't have to throw exceptions then.
