Generate server scaffold from OpenAPI spec

[finn-block]

currently the OpenAPI spec and the server are manually updated separately. We should manually write one and automatically generate the other. Ideally write the spec and generate the server.

oapi-codegen is a nice generator.

Oooh! This looks fun, and I love OpenAPI! @blackgirlbytes would it be alright if I grabbed this one for y'all?
