The maps clusters now listen for HTCP on 239.128.0.114, can you configure your software to emit the HTCP to that address and then we can test whether it's functioning correctly cross-DC to the eqiad maps varnishes?

re-assigning to Yuri to actually implement the HTCP-sending part so we can observe whether it works
