HOTFIX: Fix HerderRequest.compareTo()
With KAFKA-3008 (#1788), the implementation does not respect the contract
that 'sgn(x.compareTo(y)) == -sgn(y.compareTo(x))'
This fix addresses the hang with JDK8 in DistributedHerderTest.compareTo()

> Connect should parallelize task start/stop
> ------------------------------------------
>
> Key: KAFKA-3008
> URL: https://issues.apache.org/jira/browse/KAFKA-3008
> Project: Kafka
> Issue Type: Improvement
> Components: KafkaConnect
> Affects Versions: 0.9.0.0
> Reporter: Ewen Cheslack-Postava
> Assignee: Konstantine Karantasis
> Priority: Minor
> Fix For: 0.10.2.0
>
>
> The Herder implementations currently iterate over all connectors/tasks and
> sequentially start/stop them. We should parallelize this. This is less
> critical for {{StandaloneHerder}}, but pretty important for
> {{DistributedHerder}} since it will generally be managing more tasks and any
> delay starting/stopping a single task will impact every other task on the
> node (and can ultimately result in incorrect behavior in the case of a single
> offset commit in one connector taking too long preventing all of the rest
> from committing offsets).
