title: Terraform: Can I set variable type = any dict/object
body: <p>Is there a way to allow any type of dictionary/object as an input variable?</p>
  <p>I have a module to create cron expressions with lambda and I'm trying to add a variable to take in a dictionary to pass into the resource call.</p>
  <p>I'd like just allow any dictionary of any length. With any type for the keys and values in it.</p>
  <p>Initially, I tried just:</p>
  <pre><code>variable vars {
    type = object
  }
  </code></pre>
  <p>But that isn't allowed.</p>
  <p>Right now I just have the type empty, so it will accept anything, but that doesn't seem like good practice.</p>
