Add method to add a secondary destination in BaseMessage

[whichwit]

Request from Aihua T. (UT):

I would like a method to add a second destination in BaseMessage. The existing method:

public void setMessageDestination(String value) {
  messageHeader.getDestination().clear();
  MessageHeader.MessageDestinationComponent dest = new MessageHeader.MessageDestinationComponent();
  dest.setEndpoint(value);
  messageHeader.getDestination().add(dest);
}

Is this a reasonable ask? Surely you can do something akin to...

messageheader.getDestination().add(new MessageDestinationComponent(value));

and writing a function to do one line is often a bad-smell.

The overriding setter is just a guardrail for useability but if they need a 2nd destination using the components as HAPI intended would be a reasonable expectation of an implementor.
