Configuration File Formatting

Format configuration files for better maintainability

BEFORE (Minified JSON) 
{"server":{"host":"localhost","port":3000,"ssl":{"enabled":true,"cert":"/path/to/cert.pem","key":"/path/to/key.pem"}},"database":{"type":"postgresql","connection":{"host":"db.example.com","port":5432}}}
AFTER (Beautified JSON) 
{
  "server": {
    "host": "localhost",
    "port": 3000,
    "ssl": {
      "enabled": true,
      "cert": "/path/to/cert.pem",
      "key": "/path/to/key.pem"
    }
  },
  "database": {
    "type": "postgresql", 
    "connection": {
      "host": "db.example.com",
      "port": 5432
    }
  }
}
