Add authored examples to MAN and HTML documentation

---------------------------------------------------

This customization allows authored examples in ReST format to be

inserted into the generated help for an Operation. To get this to

work you need to:

* Register the ``add_examples`` function below with the

``doc-examples.*.*`` event.

* Create a file containing ReST format fragment with the examples.

The file needs to be created in the ``examples/<service_name>``

directory and needs to be named ``<service_name>-<op_name>.rst``.

For example, ``examples/ec2/ec2-create-key-pair.rst``.
