Grafana export endpoint

[Randoooom]

https://github.com/grafana/grafana-infinity-datasource does not support gRPC, therefore we would have to either deploy an http service or we just setup an envoy sidecar which takes care of the http/json to gRPC transcoding.

I would prefer the envoy variant

How to achievie:

• Auth via OAuth passthrough
• we would need to return the prompts / targets to the user somehow
  • may cache all prompts / targets?
  • return the filtered cached based on the OAuth
• fetch corresponding responses

did reconsider this approach: We wouldnt be able to implement all requried features with grafana (event while using infinity). Therefore we should implement all of this in the webinterface
