Configure scraping and dashboarding of the Wemo Insight Switch

All of the systems in the lab currently draw power through a Wemo Insight Switch that measures power usage. The switch provides an API that is queryable, and there are some packages that wrap it for Python or Python with aiohttp, and there are Prometheus client libraries for asyncio and the official (synchronous) Python client.

I should make an application that serves as a stateless exporter of the WeMo, a scraper config for it, and should include those metrics in my dashboarding on the cluster page.
