* Increase timeouts in the `RoundRobinDispatcherConcurrentTests` and `ManualFlowTests` * Fix `PollerAdviceTests` to re-use `TaskScheduler` from the ctx instead of local, not closed instance * Use `OnlyOnceTrigger` instead of local implementations * Change the `primary` `Trigger` bean to the `PeriodicTrigger` as well. The minimum interval for the `CronTrigger` is 1 seconds - it doesn't matter for this test-case
