Possibility to define an actor for controlling the routing logic from external stimuli (e.g. monitoring metrics). This actor will be a child of the router "head" actor. Management messages not handled by the "head" actor are delegated to this controller actor.

A router pool that uses round-robin to select a routee. For concurrent calls, round robin is just a best effort.
The configuration parameter trumps the constructor arguments. This means that if you provide
nrOfInstances
during instantiation they will be ignored if the router is defined in the configuration file for the actor being used.Supervision Setup
Any routees that are created by a router will be created as the router's children. The router is therefore also the children's supervisor.
The supervision strategy of the router actor can be configured with #withSupervisorStrategy. If no strategy is provided, routers default to a strategy of “always escalate”. This means that errors are passed up to the router's supervisor for handling.
The router's supervisor will treat the error as an error with the router itself. Therefore a directive to stop or restart will cause the router itself to stop or restart. The router, in turn, will cause its children to stop and restart.
