title: Add custom errors to vee validator(ErrorBag)
body: <p>Is it possible to add custom errors into the ErrorBag</p>
  
  <p>I am using nuxtjs. i have registered vee-validate into my plugin via nuxt.config.js</p>
  
  <p>It works fine However</p>
  
  <p>I want to use the same error code within the template</p>
  
  <p>ex:</p>
  
  <pre><code> &lt;template&gt;
     &lt;div v-if="errors.all().length&gt;0"&gt;
         //loop through
     &lt;/div&gt;
   &lt;/template&gt;
  </code></pre>
  
  <p>i am using axios to fetch user information. 
  if the request doesnt return my expected data set. i was thinking i could simply</p>
  
  <pre><code> this.errors.push('this is my error message') //-&gt; or some variant of this
  </code></pre>
  
  <p>When i do this i get that this.errors.push is not a function</p>
  
  <p>I know that </p>
  
  <pre><code>this.errors = ErrorBag{ __ob__: Observer} //-&gt; has items and a vmId attributes
  </code></pre>
  
  <p>If i amend the code to push onto ErrorBag i get push of undefined</p>
