https://build.spring.io/browse/INT-SI50X-20 Looks like 5 seconds is not enough to wait for the test completion, especially on CI server * Refactor `PollingConsumerEndpointTests` to use `OnlyOnceTrigger` from the test-support module instead of local `Trigger` implementation * Increase timeout for latch in the `OnlyOnceTrigger` to 10 seconds **Cherry-pick to 5.0.x**
