Users need to change job submission script and provide related configs explicitly through --config, instead of using --config-factory and --config-path to load local file.

Config Rewriters won't be invoked on job runner anymore, i.e. if the config rewriter is rewriting the job submission configs, it won't take effect anymore, users are expected to pass them explicitly.

Rollback Plan

In case of a problem in Samza 1.4, users are able to rollback to Samza 1.3 and keep the old start up flow using --config-path & --config-factory.
