support MicroProfile OpenAPI 3.x

[dcdh]

I am working on Quarkus application and quarkus used open api to describe rest endpoints.

This issue add a new module to support MicroProfile OpenAPI 3.x

MicroProfile OpenAPI 3.x is based on Swager 2.x so I write this module following the jsonschema-module-swagger-2.

Notable changes : the @ArraySchema does not exists on OpenAPI side, and some methods are not deprecated and others not implemented.

You could check the changes between theses two modules.

Here is the Pull Request

Hi @dcdh,

I am happy to take a new module on board and will look at your PR.
