调用此方法时，需新建一个YamlUtils().set_yaml(file_name,content)
用原来的设置不会生效
default_flow_style=False : 表示dump后的字典数据全部以yml格式显示,默认为为True
sort_keys=False : 表示dump后的字典数据按原有的顺序示，为True时按字母的排序展示，默认为为True

yml文件原有数据顺序：
更改字段值后的顺序：
出现原因是：
yaml.dump(content,f,allow_unicode=True, default_flow_style=False,sort_keys=True)
该行的代码中sort_keys的默认值为True，改为Flase后可修复代顺序变化的问题
