Adding the section for event call back.

eg:-
- name: example event callback
  description: >
    'Callbacks are actions PDM should take when instructed to do so.

    Some callback types refer to a group of paths and group of properties
    in a similar fashion as the property watch directive.

    The event callback creates the event D-Bus object with the given name
    and the event message.
    eg /xyz/openbmc_project/events/test/<id>'
  class: callback
  callback: event
  paths: example path group
  properties: example property group
  eventName: test
  eventMessage: "Test configuration changed."

When fully implemented, event callbacks will create DBus objects for
preconfigured DBus events.
