That's only partially correct. Yes, cos-proxy requires "monitors", which
is not (directly) provided by OpenStack charms, but that's exactly how
the old LMA stack has always operated:

```
# LMA, legacy

Principal charm (Keystone/Cinder/etc...) --nrpe-external-master--> nrpe
--monitors--> Nagios

# COS, currently supported

Principal charm (Keystone/Cinder/etc...) --nrpe-external-master--> nrpe --monitors--> cos-proxy --cos_agent--> grafana-agent -> COS
```

In other words you can replace the LMA stack with COS by inserting cos-
proxy between nrpe and COS. No other change is necessary "left" of nrpe.
Hopefully this makes sense.
