This is a feature we want to backport from Lagom which essentially works like a sharded singleton. A number of actor instances are kept alive and balanced across the cluster.

The main motivation to bring it into Akka is the use case where workers that update projections. By tagging akka-persistence events with N different tags and then running N workers, one for each tag which consumes that partition of the events and updates a projection.
