Leonard Lyubich 21133aee2f [] container/load: Implement route builder based on placement
Implement route Builder interface on wrapper over the container placement
builder, Component implies exactly one transfer to each of the most weight
nodes of the container (according to some weighing algorithm).
Implementation is planned for use when transferring local estimates of
storage nodes.
