Registers a ContainerPlacement action, this method is invoked by ContainerPlacementRequestAllocator. {@link ContainerProcessManager}
needs to intercept container placement actions between ContainerPlacementRequestAllocator and {@link ContainerManager} to avoid
cyclic dependency between {@link ContainerManager} and {@link ContainerAllocator} on each other
