Fix: time series data request exceeding limit

[lim-yoona]

Description

I implemented the logic of multiple requests in the QueryRangeMetric function of internal/metrics/common/common.go. I think it is more complicated to get the time information from the name parameter, so I need to pass in three parameters: start, end and interval. This results in many calls to this function needing to be modified, so there are more changes.

If it feels inappropriate, I will modify the code again.

Add incoming parameters:

func QueryRangeMetric(name string, start, end, interval uint64, results *chan MetricResult) {}

or getting the time information from the name parameter:

nameSlice := strings.Split(name,"&")
str := nameSlice[0]
start := nameSlice[1][6:]
end := nameSlice[2][4:]
interval := nameSlice[3][5:]

Then use strconv to convert the string to uint64.
