Add api testing lesson.

[linkonsat]

Description
Currently, the RoR path does not have any testing lessons for Rails. This issue aims to resolve by adding a new lesson for API testing within a new testing section in the Ruby on Rails curriculum. There are many useful resources that go over system testing and you can find this within Rails guides here and by googling resources on it. This lesson should follow the style guide.
