mod_authz_delegate: make resistant against startup order issues There is no guarantee that the target_host gets activated and initialized before the host this module is loaded on. As add_default_permission is called during load time by many modules, we need to be prepared to queue stuff.

local count_registering = module:measure("user_registering", "rate");
local count_registered = module:measure("user_registered", "rate");

module:hook("user-registering", function ()
	count_registering();
end);

module:hook("user-registered", function ()
	count_registered();
end);
