    /**
      Allows for runtime registration of handler functions that override the default deprecation behavior.
      Deprecations are invoked by calls to [Ember.deprecate](https://emberjs.com/api/classes/Ember.html#method_deprecate).
      The following example demonstrates its usage by registering a handler that throws an error if the
      message contains the word "should", otherwise defers to the default handler.
    
      ```javascript
      Ember.Debug.registerDeprecationHandler((message, options, next) => {
        if (message.indexOf('should') !== -1) {
          throw new Error(`Deprecation message with should: ${message}`);
        } else {
          // defer to whatever handler was registered before this one
          next(message, options);
        }
      });
      ```
    
      The handler function takes the following arguments:
    
      <ul>
        <li> <code>message</code> - The message received from the deprecation call.</li>
        <li> <code>options</code> - An object passed in with the deprecation call containing additional information including:</li>
          <ul>
            <li> <code>id</code> - An id of the deprecation in the form of <code>package-name.specific-deprecation</code>.</li>
            <li> <code>until</code> - The Ember version number the feature and deprecation will be removed in.</li>
          </ul>
        <li> <code>next</code> - A function that calls into the previously registered handler.</li>
      </ul>
