Description

Introducing a ZK communication version protocol will allow us in the future to detect incompatible versions of participants at the start of the job and stop them right away.

In this case we can allow participants of different build version, but same communication protocol version to work together.

One option would be to write the protocol version as a data of the root zk node of each job.
