What would you like to be added:

In the future, we may need a command line tool to install specific version of Kmesh with one click.

But since the project is still in its early stage, we may need some simpler methods quickly to implement this.

Why is this needed:

Until now, three versions of Kmesh has been released.

But I find there is no easy way to install specific version of Kmesh except directly modifying the image tag in the yaml.
