Print build info

The buildinfo API returns information about the current build for a runtime component. This information may be useful if you need to contact support:

1. Execute the following command to forward to port 8843. This allows you to call the API in the pod:

   kubectl port-forward -n namespace apigee-runtime-pod-name 8843:8843

2. Call the buildinfo API:

   curl -v https://0:8843/v1/buildinfo -k
