 * There are currently 2 distinct analytics logging methods
 * 1. `stdout`: used in dev and compatible with https://github.com/meetup/blt-fluentd
 *    in k8s-based applications in GCP
 * 2. Google Pub/Sub, which is used in GAE and any environment with GOOGLE_APPLICATION_CREDENTIALS
 *    environment variable set to point toward Google JSON client credentials file
