Devices for metrics and health

lawik commented 3 months ago

The start of Device health reporting!

This adds Load avg, memory use, and CPU temp to the Device show page. The data we receive, and store, from the device is a lot more complete, but we have kept it simple for now.

A few bullet points:

the device health data is requested from Hub once an hour (configurable)
when you are viewing a device it will start requesting health data once a minute until you leave the device page
for the time being, only 48 device reports are kept for a device

fyi @joshk

I want to test it with poser and a real device, it still needs some tests.

I think exposing it in UI can happen separately unless I get frisky :D
