首先，先对动态菜单的概念、操作、流程进行约束：
1.Host和各个Tenant有自己的自定义菜单
2.Host和各个Tenant的权限与自定义菜单相关联
2.Tenant有一套默认的菜单，规定对应的TenantId=-1，在添加租户时自动将标准菜单和标准菜单的权限初始化到添加的租户

    public class AbpMenus : Entity<int>
    {
        public string MenuName { set; get; }
        public string PageName { set; get; }
        public string Name { set; get; }
        public string Url { set; get; }
        public string Icon { set; get; }
        public int ParentId { set; get; }
        public bool IsActive { set; get; }
        public int Orders { set; get; }
        public int? TenantId { set; get; }
    }

如果翻过源码中实体的定义，可以发现很多实体的继承，例如：

1.继承接口 IMayHaveTenant，继承后生成的sql语句将自动增加TenantId的查询条件，表中必须包含TenantId列
2.继承接口 IPassivable，继承后表中必须包含IsActive列
3.继承接口 FullAuditedEntity<TPrimaryKey> TPrimaryKey可以是long、int等值类型，必须包含IsDeleted、DeleterUserId、DeletionTime，其中这个接口
        还继承了AuditedEntity<TPrimaryKey>, IFullAudited, IAudited, ICreationAudited, IHasCreationTime, IModificationAudited, IHasModificationTime, IDeletionAudited, IHasDeletionTime, ISoftDelete，这些父类型、接口的定义自己F12就可以看到

NavigationManager的非静态构造函数中去获取已经本地化的Menus，但是本地化Menus因为是在初始化时，程序的初始化我们无法获取到当前的Tenant信息，所以只能将获取Menus的地方推迟，放在倒数第二个类UserNavigationManager里面的GetMenuAsync方法中，我们来看下GetMenuAsync
