Support to custom response class.

[yurirnascimento]

Related to #11

I added the possibility to inform a custom class to return as a response in addition to the default SaloonResponse.

Changes:

• Change the SaloonRequestInterface to have getResponseClass method.
• Create a folder to contain all custom responses
• Create a invalid response to test
• Creeate a CustoUserResponse
• Create a UserResponse to show how to use

Added tests:

• check if the class extends SaloonResponse
• check if the response is the class informed
• check if the request with custom response work

I tried to keep the existing coding style.

hope this can help.

This PR looks great, thank you @yurirnascimento. I need to take a proper look at the code on my laptop but thanks for contributing this.

Looks good, I think we should have a connector that can be defined on the response too, which should run the same code as the request. So many could be dedicated to a trait like "HasCustomResponses"

This looks fantastic! Happy with the code, there's some formatting things I'd like to quickly fix but I'll write a commit for you, but functionality wise this looks great. I will also draft some documentation before the release.

Thanks for the hard work @yurirnascimento and thank you everyone else for helping with the idea.

Sorry just a couple other things

[Sammyjo20]

Thanks for this awesome PR @yurirnascimento! Going to write up some documentation now... 💅

[Sammyjo20]

Written up some docs in the “Responses” section.
