Deploy to new members in cluster, see #2103

Browse source 
* Config max-nr-of-instances-per-node
* selectDeploymentTarget that takes max-nr-of-instances-per-node
  and nr-of-instances into account
* Deploy when new member added or removed
* Moved routeeProps to RouteeProvider constructor, needed for
  this feature, but also simplifies createRoute, createRoutee,
  and resize, since routeeProps doesn't have to be passed around.
