Title: Making task assignment policy pluggable.

Once we have enough information via probes or stale state, we still need to
assign tasks to nodes based on estimated resource endowments. This patch
abstracts out policy used to make that assignment, and introduces a simple
policy based on CPU usage which we want for our prototype experiments.
