Take StackOverflow into account when building community members rating

[samdark]

As @InsaneSkull pointed in a slack chat:

• SO Yii2 Top Users : https://data.stackexchange.com/stackoverflow/revision/944884/1172649/top-yii2-users
• https://data.stackexchange.com/stackoverflow/query/new
• https://api.stackexchange.com/docs

That could be an interesting idea to count SO reputation when building community members rating https://www.yiiframework.com/user/halloffame and probably issuing badges: https://www.yiiframework.com/badges
