MEDIUM: checks: add send/expect tcp based check
This is a generic health check which can be used to match a
banner or send a request and analyse a server response.
It works in a send/expect ways and many exchange can be done between
HAProxy and a server to decide the server status, making HAProxy able to
speak the server's protocol.
It can send arbitrary regular or binary strings and match content as a
regular or binary string or a regex.
