User interface for arazzo support

[Sperez96]

Hello, it could be interesting to add graph support through components to the openapi document, which allows relating endpoints/examples between calls, and that would translate into arazzo workflows, and that you could execute all the workflows as test cases in each deployment, reporting the features that are considered OK / KO. This way you can easily define reusable test cases, and the http requests could even be exported to other tools like Postman, to execute step by step.
