sonic-telemetry_client.yang and dialout_client.go prefix requirement does not match

[amareshpGithub]

In "https://github.com/sonic-net/sonic-buildimage/tree/master/src/sonic-yang-models/yang-models/sonic-telemetry_client.yang" prefix expect as "Subscription|DestinationGroup"

            leaf prefix {
                type string {
                    pattern 'Subscription|DestinationGroup';
                }
            }

But the in "https://github.com/sonic-net/sonic-gnmi/blob/master/dialout/dialout_client/dialout_client.go", it expect as "DestinationGroup_" and "Subscription_" as mentioned below. Is there any new dialout client?

else if strings.HasPrefix(key, "DestinationGroup_") {
destGroupName := strings.TrimPrefix(key, "DestinationGroup_")
if destGroupName == "" {
return fmt.Errorf("Empty Destination Group name %v", key)
}
// Close any client intances targeting this Destination group

} else if strings.HasPrefix(key, "Subscription_") {
name := strings.TrimPrefix(key, "Subscription_")
if name == "" {
return fmt.Errorf("Empty Subscription_ name %v", key)
}
csub, ok := ClientSubscriptionNameMap[name]
if ok {
