alidns: migrate to SDK v2

[ldez]

The Alibaba Cloud V1.0 Go SDK has entered End-of-Support (March 1, 2025) and is no longer recommended for use.
New users should directly use the V2.0 Go SDK;
https://github.com/aliyun/alibaba-cloud-sdk-go

But there is no link inside the readme about this SDK v2.

There is a link inside the "About" section to an org: https://github.com/aliyun/alibabacloud-sdk

I found 2 repositories:

• https://github.com/alibabacloud-go/alidns-20150109
• https://github.com/aliyun/alibabacloud-go-sdk/tree/master/alidns-20150109

The 2 repositories contain the same module: github.com/alibabacloud-go/alidns-20150109/v4
The code seems identical.

The main file is client/client.go: a 2.03 MB file with more than 67k LOC, too large to be displayed inside GitHub.

There is a light migration guide, but the SDK APIs are closed.

• https://github.com/aliyun/alibabacloud-go-sdk/blob/master/docs/Usage-EN.md#demo

The size of the lib inside the GOCACHE is reduced:

SDK v1:

MODULE	SIZE
github.com/aliyun/alibaba-cloud-sdk-go@v1.63.100	88.654 MiB

SDK v2:

MODULE	SIZE
github.com/alibabacloud-go/alidns-20150109/v4@v4.5.10	2.044 MiB
github.com/aliyun/credentials-go@v1.4.5	359.074 KiB
github.com/alibabacloud-go/darabonba-openapi/v2@v2.0.11	148.271 KiB
github.com/alibabacloud-go/tea@v1.2.2	129.162 KiB
github.com/alibabacloud-go/openapi-util@v0.1.1	53.163 KiB
github.com/alibabacloud-go/tea-utils/v2@v2.0.6	44.850 KiB
github.com/alibabacloud-go/alibabacloud-gateway-spi@v0.0.5	31.445 KiB
github.com/alibabacloud-go/tea-xml@v1.1.3	19.267 KiB
github.com/alibabacloud-go/debug@v1.0.1	15.773 KiB
github.com/alibabacloud-go/endpoint-util@v1.1.0	4.577 KiB

Total: ~2.83 MiB

And it decreases the binary by ~5MB.

2 MB in only one file 😸
