This PR addresses #378, and since we will need to modify the task estimator interface I saw this as a good opportunity to also resolve #331.
We modify the task estimator interface here by changing
scale_up_leaf_nodetoplan_leaf_node, whereplan_leaf_nodenow returns aPlannedLeafNodestruct that optionally contains a list of URLs that can be used to assign tasks to specific worker nodes.The interface allows for flexible routing of tasks to workers for e.g. consistent routing / cache locality.
