[Bro] logging locally and to remote logger

Ah, I think there is some confusion. Out of the box if you log locally as
well as using a remote logger (2.5), the logs locally get shoved into
worker buckets. I was hoping to see how it would be possible to get
standard cluster behavior, where all workers log locally to one bucket
instead of each worker having its own bucket.
Anyone know why this logs to separate buckets in the first place?
