-------------------------------

Let me backport this to branch-1. I tried both combinations of old client to new server and new client to old server and all worked fine as expected.

> In the operation of a cluster, we usually want to know which clients are using the HBase client with critical bugs or too old version we will not support in future.
> By adding version info in RPC connection header, we can get these informations from audit log and promote them upgrade before a deadline.
> Discussions and suggestions are welcomed. Thanks.
