Feature: #593 - Add event to assign own data to moduleTemplate 

See Issue 593

Description 

Adding your own data to module templates is not so easy. In order to assign own data to the moduleTemplate, you need a way to assign your own data if you do not want to develop your own backend module.

The \Extcode\Cart\Event\Template\Components\ModifyModuleTemplateEvent event is dispached in the OrderController for the backend module.

An own EventListener can use the methods getRequest(), getSettings(), getModuleTemplate() to retrieve all the necessary information to assign custom data. The request object can be used to assign data for specific actions.

Impact 

No impact is expected.
