Description

Although the Samza RunLoop is single-threaded, there are other threads used in important areas. e.g. BrokerProxy. It's useful to log the thread name to help reason about how the threads are interacting.

Also, the time stamps are currently logged with second granularity which can make it hard to identify events that happen on sub-second time scale.

This ticket is to update the log4j configurations in the samza and hello-samza repositories to include millisecond timestamp granularity and threadname.
