Client Version Negotiation

[wey-gu]

Introduction

Introduce a mechanism to enable the client-side to negotiate server version, thus choosing corresponding thrift module, this will enable clients to be with backward compatibility.

Thus, for clients, 3.1.0 could support 3.0.0 server-side, too, and we could release and plan clients on fewer branches, and version/release for clients can be planned/focused on improvements rather than simply replace thrift.

Thus, console, http-gateway, operators, etc could benefit from it, too.
