Break GWCelery nagios check into several services
I am guilty of basically ignoring Nagios alerts from GWCelery. The reason is that the GCN connection is flaky and goes up and down several times a day. Since there is only one Nagios service for each GWCelery deployment, the flakiness of that one subsystem dilutes the urgency associated with other services. We should break the GWCelery nagios check into several individual services so that we can set alert notifications on the other, non-flaky components.
