title: How to make a cooldown system with discord.py?
body: <p>Let's say I have two commands...</p>
  <ul>
  <li><code>hi 1</code> that sends hi once to user and starts a cooldown of 500 seconds</li>
  <li><code>hi 2</code> that sends hi twice to user and starts a cooldown of 1000 seconds</li>
  </ul>
  <p>Now when I type <code>hi 1</code> it should not respond to me when I type <code>hi 2</code>.
  Something like a shared cooldown system!</p>
  <p>How can I do that?</p>
  <p>I am currently using this:</p>
  <pre><code>@commands.cooldown(1, 5, commands.BucketType.user)
  </code></pre>
  <p>Which allows me to use the multiple commands without stopping for cooldown on a previous command.</p>
