Feat: Expose routes to be able to generate swagger docs etc

[marvinhagemeister]

Feature request from twitter:

Is it possible to also generate openapi/swagger docs?

I think a good way to explore this would be a way to expose the final routes to plugins.

[fdemir]

is it possible to get handlers from a plugin?

[marvinhagemeister]

No, neither routes, not available handlers are exposed to plugins.

Something like https://github.com/tazo90/next-openapi-gen would be nice.
