Sensors metrics for the hostmetrics receiver

[imiric]

Hi, I'm wondering if there would be interest in adding a new scraper to the hostmetrics receiver that exposes the host's sensors (temperature) metrics. I'm surprised it's not already supported, since it's fairly essential information to keep track of. I didn't find any discussion or feature request for it.

The gopsutil module already supports gathering it via the sensors package, so this should presumably be a relatively simple addition. I'm thinking that a separate sensors scraper makes sense, instead of adding it to the existing system one, but I could be convinced otherwise. It could be a single sensors.temperature gauge metric, with name, high, and critical attributes. Or it could also be under system as system.temperature...?

I would be willing to try implementing this myself. Just wanted to check if there's interest in merging it to the contrib project, and if so, some general design suggestions would be appreciated.

Cheers!
