mod_prometheus: Ensure mod_http is loaded where the http interface is exposed (thanks Martin) Loading mod_http globally does not have the desired effect, it needs to be loaded in the host context where module:provides is called.

module:hook("message/host", function (event)
	local stanza = event.stanza;
	if #stanza.tags == 1 and stanza.tags[1].attr.xmlns == "http://jabber.org/protocol/chatstates" then
		return true;
	end
end, -10);
