Description

A good command line interface uses --verbose or --debug to control verbosity for users and contributors to get more info about what is going on in the program. Currently IIUC a user has to tweak JUL which is quite a poor experience and Java-centric rather than a good command line interface. We should add support for this alongside our other tools (like pipeline options parsing) for making it easy to build a pipeline main().

Note that this is for the construction & submission side / core SDK. Each runner has its own needs as far as how to control the worker logging, though it is probably still better to have a general way.
