> Add long UTF serializer/deserializer

> DataOutputSerializer.writeUTF has a hard limit on the length of the string
> (64k). This is inherited from the DataOutput.writeUTF method, where the JDK
> specifically defines this limit [1].
> For our use-case we need to enable the possibility to serialize longer UTF
> strings, so we will need to define a writeLongUTF method with a similar
> specification than the writeUTF, but without the length limit.
> Based on the discussion on the mailing list, this is a good additional
> serialization utility to Flink [2]
