Upstream GCP Self-Signed JWT Policy

CAUTION: This policy only works with certain Google APIs. In most cases, the Upstream GCP Service Auth should be used.

This policy adds a JWT token to the headers, ready for us in an outgoing request when calling a GCP service (e.g. Cloud Endpoints / ESPv2). We recommend reading the serviceAccountJson from environment variables (so it is not checked in to source control) using the $env(ENV_VAR) syntax.
