title: Angular CDK Drag and Drop: Cancel drag-action
body: <p>With the new drag and drop feature of the @angular/cdk (I'm currently using version 7.0.0-beta.2), is it possible to cancel a drag-action?</p>
  
  <p>I did not find a matching function on 'CdkDrag' which could do the trick.</p>
  
  <p><strong>Edit from 2019-01-10</strong></p>
  
  <p>Thanks for the responses so far. I guess I wasn't clear enough, though: I'm looking for a way to cancel a drag-action which is already in progress. I. e. while dragging an item, I want to have the possibility to make that item return to the container where it comes from (e. g. by pressing the Escape key).</p>
  
  <p>Any ideas?</p>
