An example for using pgwire as proxy

[sunng87]

This example is going to demonstrate how to use pgwire + tokio_postgres as a proxy of postgresql. I just implemented simple_query subprotocol for referencing. For a complete proxy solution, we will need to add some client side support for pgwire to drop tokio_postgres in proxy scenario.
