relay bot cannot update cached state on single-host networks

[jack-avery]

Single-host network meaning both metrics and a dedicated server are on the same host. Currently this is impossible and I would like it to also be compatible with having other hosts separate from the metric/dedi host. Will likely involve calculating whether the host also is the metrics host, somehow

Possibly fixed with 5c0b579, pending testing

Handled nicely without a convoluted tunnel by using named networks and Jinja2 templating.

yeah the relay bot freaks out a tiny bit with this. specifically it cannot update state for /servers, but message relaying and /rcon are both still functional. low prio. todo eventually
