fix default setting

[brucelwl]

1、需要通过AnnotatedMethodElement 获取里面的注解信息及引用对象,但是这个类是私有的, 将他改成public,比较合理.

2、还有 DubboConfigBindingBeanPostProcessor 将这两个属性值固定死了, 无论外部bean怎么配置都会在这里改变,所以将这两个属性改成局部变量比较合理
private boolean ignoreUnknownFields = true;
private boolean ignoreInvalidFields = true;

这是2.7.x版本，请看2.6.x 版本：#4955
