Is your feature request related to a problem? Please describe.
It's not realy a problem, but the provider prometheus is not compatible with thanos.
When I setup thanos url I have this issue :

prometheus scopes are invalid: { "connectivity": "'NoneType' object is not iterable" }

Thanos does not support api/v1/alerts.

It would be great if provider prometheus was compatible both with prometheus and thanos (same engine search).

Describe the solution you'd like
fix provider prometheus to work with thanos

Describe alternatives you've considered
Develop new provider "thanos"
