title: Is there a way to validate dynamic key names in a Joi schema?
body: <p>Is there a way I can validate a value like this with <code>Joi</code> so that I can verify it is an object with zero or more keys (of any name) and that each have values of either a string, number or boolean?</p>
  
  <pre><code>{
    dynamicallyNamedKey1: 'some value',
    dynamicallyNamedKey2: 4
  }
  </code></pre>
