REGTESTS: provide a reverse-server test with name argument

This regtest is similar to the previous one, except the optional name
argument is specified.

An extra haproxy instance is used as a gateway for clear/TLS as vtest
does not support TLS natively.

A first request is done by specifying a name which does not match the
idle connection SNI. This must result in a HTTP 503. Then the correct
name is used which must result in a 200.
