Christian Kreibich ac40d5c5b2 Remove periodic pinging of controller by agents ... This changes the agent-controller communication to remove the need for ongoing pinging of the controller by agents not actively "in service". Instead, agents now use the notify_agent_hello event to the controller to report only their identity. The controller puts them into service via an agent_welcome_request/ response pair, and takes them out of service via agent_standby_request/response. This removes the on_change handler from the set of agents that is ready for service, because not every change to this set is now a suitable time to potentially send out the configuration. We now invoke this check explicitly in the two situations where it's warranted: when a agent reports ready for service, and when we've received a new configuration.		2021-12-21 16:44:04 -08:00
