Description

This Jira introduces a new Java bridge for Drivers implemented in alternative languages. It provides the following artifacts (note: client driver refers to the application driver implemented in an alternative programming language):

1. A generic framework for passing information between the Java driver and the client driver.
2. A gRPC based implementation of the bridge that passes information via protocol buffers over gRPC. 
3. Protocol buffer definitions for all information that flows between the Java driver and the client driver.
4. A Java implementation of the driver client that can be used for developing unit tests and serve as a template for implementing a driver client (say in C#).
5. Extensions to fail based unit tests that cover the Java bridge and client.
