    Avoid overflow errors with timestamps

    Some comparisons with timestamp values are not safe. This comparisons can 
trigger errors that were found in other Apache projects, e.g. KAFKA-4290. 
    I changed those comparisons according to what the Java documentation 
recommends to help preventing such errors.

>
> The timeout passed to {{WorkerCoordinator.poll()}} can overflow if large 
> enough because we add it to the current time in order to calculate the call's 
> deadline. This shortcuts the poll loop and results in a very tight event loop 
> which can saturate a CPU. We hit this case out of the box because Connect 
> uses a default timeout of {{Long.MAX_VALUE}}.
