title: Closing Connection on SailsJS
body: <p>I'm using Sails JS with sails-mysql 0.12.1.
  And I'm utilizing query() method to do query from database, but lately I'm getting Too Many Connection SQL problems.</p>
  
  <p>This is my setting:</p>
  
  <pre><code>db: {
      adapter: 'sails-mysql',
      host: 'my db',
      user: 'my user',
      port: 3306,
      password: 'my password',
      database: 'l2alpha',
      connectionLimit: 0,
      pool: false
    },
  </code></pre>
  
  <p>Just wondering if this sails-mysql close the connection automatically after doing the query? Because I cannot find how to close the connection manually on the documentation</p>
