Description of your changes

Provides per-user Cloud Shell in VelaUX where users can execute vela or kubectl commands. Help users to quickly query information and perform advanced operations through Shell style, it includes:

1. All the capabilities of Vela CLI (within the scope of authority), users can not care about the kubeconfig and permissions.
   Highlights:
   • vela exec
   • vela logs
   • vela status
   • vela up
2. The ability of kubectl CLI (within the scope of authority);
3. Call the VelaUX API via cURL;

This feature is based on the CloudTTY, Users should enable the addon before using it.

Fixes #4052

I have:

• Read and followed KubeVela's contribution process.
