Additional ScoringImpl options

[dcmartin]

Not being a expert Go programmer, what is the expectation to extend the GetScore functionality with additional implementations, other than the current:

func calculateScore(ID string) float64 {
        cpuUsage, err := resourceIns.GetResource(resourceutil.CPUUsage)
        if err != nil {
                return 0.0
        }
        cpuCount, err := resourceIns.GetResource(resourceutil.CPUCount)
        if err != nil {
                return 0.0
        }
        cpuFreq, err := resourceIns.GetResource(resourceutil.CPUFreq)
        if err != nil {
                return 0.0
        }
        cpuScore := cpuScore(cpuUsage, cpuCount, cpuFreq)

        netBandwidth, err := resourceIns.GetResource(resourceutil.NetBandwidth)
        if err != nil {
                return 0.0
        }
        netScore := netScore(netBandwidth)

        resourceIns.SetDeviceID(ID)
        rtt, err := resourceIns.GetResource(resourceutil.NetRTT)
        if err != nil {
                return 0.0
        }
        renderingScore := renderingScore(rtt)

        return float64(netScore + (cpuScore / 2) + renderingScore)
}

We are planning to make the scoring manager a dynamic by learning on the usage patterns of the device. Based on the learning efficient device selection for offloading would be selected.
