title: Mule scatter gather custom aggregation get message processor
body: <p>Im using scatter gather with with custom AggregationStrategy. Where is several Web Service Consumers in this scatter gather. And i need to retrieve information about this consumers such as message processor name, original payload, outbound address, etc from events..</p>
  
  <p>Something like that:</p>
  
  <pre><code>public class CustomAggregation implements AggregationStrategy {
      @Override
      public MuleEvent aggregate(AggregationContext context) throws MuleException {
          for (MuleEvent event : context.collectEventsWithoutExceptions()) {
              ...get message processor name from event...
              ...get message processor payload from event...
          }
          for (MuleEvent event : context.collectEventsWithExceptions()) {
              ...get message processor name from event...
              ...get message processor payload from event...
          }
      }
  }
  </code></pre>
