ODIC/Oauth2 client for Remote Write

[Bartłomiej Płotka]

Hi

As per https://github.com/prometheus/prometheus/issues/8132 we would like to leverage OIDC for remote write natively. While we can propose and slowly discuss this upstream there is already efficient way to have sidecar that does the OIDC/Oauth2 dance and replaces bearer token on Prometheus configuration and reloads Prometheus.

Does anyone started something like this already in the open source? 🤗

Kind Regards,
