* Add support for PROXY protocol v2 in TCP listener I did not find tests for this so I added one trying to cover different configurations to make sure I did not break something. As far as I know, the behavior should be exactly the same as before except for one thing when proxy_protocol_behavior is set to "deny_unauthorized", unauthorized requests were previously silently reject because of https://github.com/armon/go-proxyproto/blob/7e956b284f0a/protocol.go#L81-L84 but it will now be logged. Also fixes #9462 by adding support for `PROXY UNKNOWN` for PROXY protocol v1. Closes #3807 * Add changelog
