…rtup Replace fixed Thread.sleep after each federated worker start with TCP port polling that returns as soon as the worker accepts a connection. Add bulk helpers that spawn N workers in parallel and wait once for the slowest to become ready, instead of summing per-worker waits. Cuts the federated CI total by ~7 min (-5%) vs main, with the biggest wins in setup-heavy suites such as transform+fedplanner (-66%) and codegen (-25%). Closes apache#2468.

WIP
This PR replace the thread.sleep with a poll based startup of federated workers in testing. The change helps our test suites to not have timeouts, or failures because of inconsistent launches of federated workers.
