The readiness probe should not depend on downstream connections. Doing so can cause unwanted downtime. See 1. This commit removes all dialing of downstream database servers as a result.
In addition, after the Proxy receives a SIGTERM or SIGINT, the readiness check will now report an unhealthy status to ensure it is removed from circulation before shutdown completes.
