Suggestion: Expose health metrics of the worker's

[mcmarkj]

Just a thought, it would be really nice that if the worker's sent health metrics to Orchard and this was exposed via the /health endpoint.

Things like CPU, Disk etc. Almost like a prometheus node_exporter but with vital stats so we can monitor how our workers are doing.

In our setup we have monitoring configured on each worker as well. So the regular exporters can monitor disk and CPU usage on the hosts. The only complication is setting up the hosts and adding some credentials. But in our case we automated it with ansible.
