When troubleshooting configuration or connection issues, it will be helpful to have the value of the HTTP Host header present in log messages emitted by HAProxy. This will help reason about HAProxy's routing decisions. For TLS connections, of course, we don't have access to the Host header, but we can use the value of the TLS SNI field. Note that the requisite `content set-var` directive MUST come before the `content accept`; HAProxy stops processing all `tcp-request content ...` directives once it has encountered a decision.
