// mostResourceScorer favors nodes with most requested resources.
// It calculates the percentage of memory and CPU requested by pods scheduled on the node, and prioritizes
// based on the maximum of the average of the fraction of requested to capacity.
//
// Details:
// (cpu(MaxNodeScore * requested * cpuWeight / capacity) + memory(MaxNodeScore * requested * memoryWeight / capacity) + ...) / weightSum

// 0 being the lowest priority and 100 being the highest.
// The more resources are used the higher the score is. This function
// is almost a reversed version of noderesources.leastRequestedScore.
