[BEAM-6872] Add hook for user-defined JVM initialization in workers
URL: https://github.com/apache/beam/pull/8104
Adds DataflowWorkerInitializer interface. Workers execute implementations of
the interface in user code when they start up via ServiceLoader. Currently
implementations are run immediately after logging is configured.
