Binary serialization format

We should provide a binary serialization format designed to reduce serialization overhead and minimizing the size of the payload that is transmitted over the wire.

It could be implemented in a very similar way as Kryo support but with interoperability in mind and ultimately we could fade Gryo out, as now with the GLVs it doesn't have a role to play.

The main benefit would be the performance improvement, making serialization and deserialization processing time negligible on both the server and the client.
