title: Make Password NumericValidator Optional
body: <p>For this application I'm working on, the password field should be able to accept only numeric password because some special users will only have to use 4 digits number to login to their dashboard. </p>
  
  <p>I commented out the <code>NumericPassowrdValidator</code>, but I got <code>KEYERROR - 'NAME'</code>. I checked the <code>contrib.auth.password_validator</code> code to see if I can add options and set either true or false to the <code>NumericValidator</code> similar to <code>MinimumLengthValidator</code>, but I can't find anything like that.</p>
  
  <p>How do I avoid the <code>NumericValidator</code>? What am I missing?</p>
  
  <pre><code>AUTH_PASSWORD_VALIDATORS = [
  {
      'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator',
  },
  {
      'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator',
  },
  {
      'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator',
  },
  {
      #'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator',
  },
  ]
  </code></pre>
