Description

This will make the semantics more clear. The resource estimator can control the speed of sending resources estimation to the slave.

To avoid cyclic dependency, slave will register a callback with the resource estimator and the resource estimator will simply invoke that callback when there's a new estimation ready. The callback will be a defer to the slave's main event queue.
