Convert Spring Fox's ApiInfoBuilder into Swagger's Info

[dsgrieve]

What's changed?

Adding recipes to handle transformation of programmatic use of Springfox API to equivalent swagger v3 API.

What's your motivation?

It is a common pattern in Springfox to do programmatic configuration as opposed to using annotations, or some combination of the two. The existing recipes handle the annotations, e.g. @apiinfo to @Info, but none for the direct use of the API.

Anything in particular you'd like reviewers to focus on?

The focus is on the most likely use case, which is that of doing programmatic configuration in lieu of using annotations.

Anyone you would like to review specifically?

Have you considered any alternatives or workarounds?

Any additional context

Let me know when you're ready for a round of feedback!

Looks like you're on the way to something that will work. I note that currently the build() method isn't being chopped off the end of the builder.

Let's also have a test case where a method returns an incomplete builder which is finalized in another method.

Great to see this come together; thanks for all the help and feedback!
