Enhancement: Display upload size in a more simplified manner along with an upload progress bar.

[kishen-v]

What happened:

RFE:
Convert upload size to the nearest KB/MB/GB, rather than bytes.
During image upload, the size is represented in bytes which can be better represented in KB/MB/GB based on the corresponding object that is being uploaded.

pvsadm/pkg/client/s3client.go

Lines 255 to 261 in ee4d801

	if _, ok := r.signMap[off]; ok {
	r.read += int64(n)
	progress := int(float32(r.read*100) / float32(r.size))
	fmt.Printf("\rUploading: Total read(bytes):%d progress:%d%%", r.read, progress)
	} else {
	r.signMap[off] = struct{}{}
	}

This can further be improved by introducing a progress bar:
