This feature returns a
probe_http_last_modifiedmetric with the content of the Last-Modified HTTP response header, if it is set by the server.That feature would be nice for (blackbox) monitoring, if a service that should regularly update a website, is working or not.
P.S.: someone encountered me to the fact, that registering the gauges shouldn't be repeated in each probe, but only at initializing the exporter. This isn't part of this PR.
