mod_http: Limit unencrypted http port (5280) to loopback by default
Since accessing this port directly over the wider Internet is unlikely
to intentional anymore. Most uses will likely be by reverse proxies, by
mistake or because of trouble configuring HTTPS.
Blocking mistaken uses is just a good thing, letting users send
potentially private things unencrypted tends to be Strongly Discouraged
these days.
Many reverse proxy setups operate over loopback, so listening there
instead of all interfaces is a net improvement.
Improved automatic certificate location and SNI support has mostly
eliminated the need for manual certificate configuration so HTTPS should
Just Work once certificates have been provided.
For local testing during development, connecting over loopback is likely
fine as well. When really needed, `http_interfaces` can still be set.
