[FLINK-2230] handling null values for TupleSerializer
When serializing, we add a `byte[] (BitSet.toByteArray)` before the fields
which indicates `null` fields.
When deserializing, we fetch the `byte[]` and obtain the underlying `BitSet
(BitSet.valueOf)`. `BitSet.get(index)` is `false` when the value is `null`. For
each field element we check if the its marked as `null` in the `BitSet` and
then pass it to the fieldSerializer.
