feature: keep trying if no Host header given

So far we would error out if no host was specified in the config or
the request. It's true that we can't do local lookup if we don't
know our own domain. However we can still use HKP.

In the future we will query leaps own API for other providers. If the
host was not set in the initial request we might even proxy a request to
ourselves. Providing the Host header will prevent an infinite loop in
that case.
