APEXCORE-606-RV: review only: optimise kryo output stream.

[brightchen]

This is a prototype of optimize kryo output stream. The main focus is avoiding memory copy and garbage collection to increase the performance.

• SerializationBuffer is the the class extends kryo Output which use the WindowedBlockStream to manage the memory.
• WindowedBlockStream is the memory management class which support manage memory blocks based windows. The windowed related function can be ignored now
• BlockStream is the super class of WindowedBlockStream which manage blocks
• CodecPerformanceTest is the class which test the performance. Please change the CodecPerformanceTest.loop to a number bigger than 100 before really do the performance test. And test the use case one by one as initialize impact the performance.
• PartitionSerde is the class serialize partition and object which can be used by BufferServerPublisher.
• BufferServerPublisher.put_new(Object) is the implementation use new stream.
