#6459 [Core feature] Enable ENV VAR secret injection in GCP Issue created by CtfChan Motivation: Why do you think this is important? This feature is already in the K8 secret manager code but is it missing in the GCP and AWS secret managers code. Goal: What should the final outcome look like, ideally? Ideally GCP users should be able to mount secrets as env vars if they would like to.
