GH-2419: DLPR: Protect Against Non-Compliant PF

Resolves #2419

We try to obtain the configured request timeout using the producer factory's
configuration properties. Some wrappers (e.g. open tracing) do not implement
this method, so fallback to the default instead of throwing an USOE.

**cherry-pick to 2.9.x, 2.8.x**

* Fix `CompletableFuture` conflicts in the tests
