Implement one of the soft constraints (#450)

Implement Instance Partitions Count soft constraint.
Evaluate by instance's current partition count versus estimated max partition count.
Intuitively, Encourage the assignment if the instance's occupancy rate is below average;
Discourage the assignment if the instance's occupancy rate is above average.

The final normalized score will be within [0, 1].
The implementation of the class will depend on the cluster current total partitions count as the max score.
