Add tornado support?

[bollwyvl]

Thanks for openapi-core!

We're looking at the challenges of updating to the more recent versions openapi-* versions on jupyterlab/jupyterlab_server#359, and will likely end up wrapping our current server (tornado) in the appropriate protocols.

Would these be welcome as PR in a future contrib/tornado?

Somebody went and already did the work 🎁

Hi @bollwyvl

there's a tornado integration project https://github.com/correl/tornado-openapi3 but it seems to be outdated. Maybe it would be worth to incorporate tornado integration to contrib/tornado (at least until 1.x version is released).
