Upstream Firebase Admin Auth Policy

This policy adds a Firebase Admin token to the outgoing Authentication header allowing requests to Firebase using Service Account admin permissions. This can be useful for calling Firebase services such as Firestore through a Zuplo endpoint that is secured with other means of Authentication such as API keys. Additionally, this policy can be useful for service content to all API users (for example serving a specific Firestore document containing configuration data)

We recommend reading the serviceAccountJson from environment variables (so it is not checked in to source control) using the $env(ENV_VAR) syntax.
