获取三方实例 部分 进行重构，使之可以进行更简单的获取对应的实例。

如之前获取对应的实例：
        switch (source.toLowerCase()) {
            case "dingtalk":
                authRequest = new AuthDingTalkRequest(AuthConfig.builder()
                        .clientId("")
                        .clientSecret("")
                        .redirectUri("http://localhost:8443/oauth/callback/dingtalk")
                        .build());
                break;
            case "baidu":
                authRequest = new AuthBaiduRequest(AuthConfig.builder()
                        .clientId("")
                        .clientSecret("")
                        .redirectUri("http://localhost:8443/oauth/callback/baidu")
                        .scopes(Arrays.asList(
                                AuthBaiduScope.BASIC.getScope(),
                                AuthBaiduScope.SUPER_MSG.getScope(),
                                AuthBaiduScope.NETDISK.getScope()
                        ))
                        .build());
                break;
               }
上面需要调用端自己去根据source编码进行 new 对应的子类，这是不合理的。调用者应该只需要关心source码和对应的配置。
现在重构后，调用端只需要传入对应的source 和自定义的配置 通过统一的入口就可以拿到正确的实例。不需要调用端做各种判断，所有逻辑判断在服务端这边做好了处理。
调用端代码如下：
        AuthDefaultSource defaultSource = AuthDefaultSource.getAuthSource("wechat_mp");
        AuthRequest request = defaultSource.getAuthRequestInstance(AuthConfig.builder()
            .clientId("a")
            .clientSecret("a")
            .redirectUri("https://www.justauth.cn")
            .build());
