feat: add an alternative to class-defined routes to remove the need of create classes if not needed

[francescovallone]

To prevent the constant creation of classes for routes it could be helpful to have a util that streamline the creation of routes.

Right now there are two proposal:

• Create a static method in the abstract class to create a Route without the needs of creating a new class.
• Make the Route class concrete and make possible to use it in the controllers.

The idea behind this proposal has been made by @exaby73 in this tweet.
