Need getMetricCaptor protected method in AbstractMessageHandler

Enhancement

Hi,

I am trying to add a new metric in my handler class. I referred to AbstractMessageChannel and its subclass AbstractPollableChannel. Here AbstractMessageChannel class has a method called getMetricsCaptor().

In my case, I want to create a new metric in handler class, hence I tried to create a subclass of AbstractMessageHandler but there is no getMetricsCaptor() method.

It will be helpful, if you can provide the same. I can raise a MR if needed.
