Mode 1752 - Fixed and updated the implementation of InfinispanBinaryStore's streaming mechanism

The information that allowed "direct" skipping was already present in the ```Metadata``` and the chunk streams: the size of a chunk, the number of chunks and the total size of the binary. Therefore, the change is _100% backwards compatible_

This PR contains 2 commits:
* one which fixes and implements the direct skipping mechanism
* one which exposes the "chunkSize" as a JSON and AS7 configuration property, allowing clients to "fine-tune" their ISPN binary storage if needed.
