// ba.score favors nodes with balanced resource usage rate.
// It should **NOT** be used alone, and **MUST** be used together
// with NodeResourcesLeastAllocated plugin. It calculates the difference between the cpu and memory fraction

// It calculates the difference between the cpu and memory fraction of capacity,

// Detail: score = (1 - variance(cpuFraction,memoryFraction,volumeFraction)) * MaxNodeScore. The algorithm is partly inspired by:
