Enhancement description

gf ctrl命令增加一个参数，可以指定生成controller文件时使用的模板。

目前模板中，controller方法模板内容为：

func (c *{CtrlName}) {MethodName}(ctx context.Context, req *{Version}.{MethodName}Req) (res *{Version}.{MethodName}Res, err error) {
// 这里其实可以写一些样板语法，比如：链路追踪的代码
return nil, gerror.NewCode(gcode.CodeNotImplemented)
}

实际业务中，这个方法中有大量的样板语法，所以希望可以由使用的人来根据需要定制模板

Enhancement description

The gf ctrl command adds a parameter to specify the template used when generating the controller file.

In the current template, the controller method template content is:

func (c *{CtrlName}) {MethodName}(ctx context.Context, req *{Version}.{MethodName}Req) (res *{Version}.{MethodName}Res, err error) {
// You can actually write some boilerplate syntax here, such as: link tracking code
return nil, gerror.NewCode(gcode.CodeNotImplemented)
}

In actual business, there is a lot of boilerplate syntax in this method, so we hope that the users can customize the template according to their needs.
