Enhancement

The old handshake Protocol::HandshakeV9 and Protocol::HandshakeResponse320 is only used with pre-4.1 MySQL clients and libraries.

This was only ever partially supported to allow old HAProxy versions to do a health check.

Removing this helps to reduce code complexity and might also improve security.
