Feature request: Data validation middleware for RESTful Event Handler

[nateiler]

Use case

Per the docs, it would be great to have standard schema validation.

I'm sure this has been discussed in some detail internally, however I would find value in input and output validation. Additionally, we have also validated against route and query params occasionally.

I stubbed out a quick middleware and pulled in some of the parser middy middleware logic. My initial thought is typing is going to be difficult. Ideally, it would be great to have the validated request body schema typing available within the route.
