JUL - Logging should be zero-conf for most users. #1654

1. JUL java.util.logging should be zero configuration for most users.
2. Work on all platforms: GAE Std 8 / Flex / GKE / GCE without modification.
3. See Logging Handler Should Have Fluentd Transport #1130 for fluentd support as well. (in GAE Flex env)

(Java 7 GAE Std / Dataproc / Dataflow is NOT Release Blocking;)

I've asked @jabubake to help you with this.
