可以看到在`validateAuthentication`方法的最后面
`$uid = $this->userAuth->authenticate($form_state->getValue('name'), $password);`
是通过这样来验证用户名密码
再分别看 `create` 方法 和` __construct` 得知 `$this->userAuth` 是因为调用了 user.auth 这个服务得到的。所以我们要做的就是重载 user.auth 这个服务

如果模块名为 my_module_name 那么名字为 MyModuleNameServiceProvider
src/ModuleNameServiceProvider.php
