Allow extensions in all OpenApi structures

Swagger documentation is outdated (https://swagger.io/docs/specification/openapi-extensions/).

Reading OpenApi sepcification (https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.0.3.md)
one can see that almost all objects can be extended with custom extensions.
