Integrate Eclipse OpenAPI API and its SmallRye implementation to inject examples into Eclipse OpenAPI models

[nandorholozsnyak]

Is your feature request related to a problem? Please describe.
Currently the project "only" supporting one OpenAPI specification library, and it is the official Swagger model library

<dependency>
      <groupId>io.swagger.core.v3</groupId>
      <artifactId>swagger-models</artifactId>
  </dependency>

but to make sure other frameworks like Quarkus can be integrated or if we reverse, devs who are using Quarkus could benefit from the tool, this integration should happen.

Things to check and investigate:

• https://github.com/eclipse/microprofile-open-api
• https://github.com/smallrye/smallrye-open-api

Describe the solution you'd like
Eclipse's OpenAPI specific libraries and the SmallRye implementation must be integrated into two separate modules:

• openapi-extender-eclipse-openapi
• openapi-extender-smallrye

And the existing openapi-extender must be renamed to openapi-extender to make sure it we can differentiate between them easily.

More information soon.
