feat: enable interface with gcp secrets manager

[ireneisdoomed]

✨ Context

I needed a way to manage secrets project wise so that the W&B API key is automatically available when running the pipeline. The Secrets Manager API provides exactly this.
Service accounts that we use for our dev development and the one used by Airflow have been granted access to this API.

🛠 What does this PR implement

access_gcp_secret is an interface to request secrets from https://console.cloud.google.com/security/secret-manager?authuser=1&project=open-targets-genetics-dev
