Return array - multiple result

It is possible to get multiple values or an array as result?
e.g. - see code
Get all the settings from a specific key (App.theme) : setting()->get('App.theme','*')
Get all the settings form a specific context : setting()->get('*','user1')
Get all the settings from a specific class : setting()->get('Log')

```
$br='
';

service('settings')->set('App.theme', 'dark', 'user1');
service('settings')->set('App.theme', 'white', 'user2');
service('settings')->set('App.theme', 'red', 'user3');
echo setting()->get('App.theme', 'user1').$br;
echo setting()->get('App.theme', 'user2').$br;
echo setting()->get('App.theme', 'user3').$br;
print_r(setting()->get('App.theme','*')).$br;
print_r(setting()->get('*','user1')).$br;

service('settings')->set('Log.location', 'site/log');
service('settings')->set('Log.date', '20220102');
service('settings')->set('Log.name', 'service');
echo setting()->get('Log.location').$br;
echo setting()->get('Log.date').$br;
echo setting()->get('Log.name').$br;
print_r (setting()->get('Log')).$br;
```

Sample database
```

`updated_at` datetime NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=armscii8 COLLATE=armscii8_bin;

-- Dumping data for table ca70_assets.da_settings: ~11 rows (approximately)
INSERT INTO `da_settings` (`class`, `key`, `type`, `context`, `value`, `created_at`, `updated_at`) VALUES

('Log', 'date', 'string', NULL, '20220102', '2023-01-02 16:13:08', '2023-01-02 16:14:10'),
('Log', 'name', 'string', NULL, 'service', '2023-01-02 16:13:08', '2023-01-02 16:14:10');
```

首先跟踪 issue 中所示的 setting()->get() 调用，以及 da_settings 表中匹配行的选择方式。使用示例数据验证键、上下文和类的通配符情况；完成的标准是每个请求的匹配都返回一个可用的 array，同时不改变单值查找。

由索引模型根据 Issue 内容生成。
