Get pvoutput code running on AWS

[flowirtz]

The code in this repository can be used to get data from pvoutput.org.
It is not run anywhere yet though.
We should turn it into something that runs on AWS so we continually get live PV power data (that we then can plot on the UI).

Ideally we achieve this by dockering the whole script, because then we can still decide whether we want to run it in an ECS cluster or via Batch or...
But also very open for other suggestions.

We do have an API Key for pvoutput.org and we already have a bucket for the output that's accessed by the frontend. Those two things should probably be env vars to the docker image.
