初始化GES管理面客户端

使用GES SDK工具访问GES管理面，需要用户初始化GES客户端。用户可以使用AK/SK(Access Key ID/Secret Access Key)或Token两种认证方式初始化客户端，示例代码如下：

• AK/SK认证方式样例代码

    String ak = "ak"; 
     String sk = "sk"; 
     String regionName = "regionname"; 
     String projectId = "project_id"; 
     GesInfo gesInfo = new GesInfo(regionName, ak, sk, projectId); 
     gesInfo.setIamEndpoint("iam_endpoint");
     gesInfo.setGesEndpoint("ges_endpoint");
     GesClient client = new GesClient(AuthenticationMode.AKSK, gesInfo);

• Token认证方式样例代码

    String domainName = "domainname"; 
    String userName = "username";
    String password = "password";
     String regionName = "regionname"; 
     String projectId = "project_id"; 
     GesInfo gesInfo = new GesInfo(regionName, domainName, userName, password, projectId); 
     gesInfo.setIamEndpoint("iam_endpoint");
     gesInfo.setGesEndpoint("ges_endpoint");
     GesClient client = new GesClient(AuthenticationMode.TOKEN, gesInfo);
