> 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).
