Add compression ratio in s3bench.go#L136-L137

[raikrahul]

We need to make some random data and sprinkle it with a const value

`
func fill_buffer(comp_percent int, size int) []byte {

	res := make([]byte, size)

	if comp_percent == 100 {
		return res
	}

	var rand_size int

	rand_size = (size * (100 - comp_percent)) / 100

	var source = rand.NewSource(time.Now().UnixNano())
	rand.New(source)
	rand.Read(res[0:rand_size])

	fmt.Println("Array:", res)

	rand.Shuffle(len(res), func(i, j int) {
		res[i], res[j] = res[j], res[i]
	})

	return res

}
`

The test for it is as follow

package main

import (
	"fmt"
	"math/rand"
	"time"
)

// fill_buffer provides a stream of compressible data
// Blanks/Zeros are added randomly amongst the random data stream
// It returns the data stream

func fill_buffer(comp_percent int, size int) []byte {

	res := make([]byte, size)

	if comp_percent == 100 {
		return res
	}

	var rand_size int

	rand_size = (size * (100 - comp_percent)) / 100

	var source = rand.NewSource(time.Now().UnixNano())
	rand.New(source)
	rand.Read(res[0:rand_size])

	fmt.Println("Array:", res)

	rand.Shuffle(len(res), func(i, j int) {
		res[i], res[j] = res[j], res[i]
	})

	return res

}
func main() {
	// fmt.Println("hello world")
	var size int

	var ratio int

	size = 4096
	ratio = 50

	resT := fill_buffer(ratio, size)
	fmt.Println(resT)
	fmt.Println("Slice:", resT)

	fmt.Println("Size was", size)

	fmt.Println("Ratio was", ratio)
}
