[FEATURE] Generate newly added APIs and plugins

[Xtansia]

Is your feature request related to a problem?

There are many APIs and plugins (e.g. security) that have been added to the OpenAPI specification and are ready to be generated in the client.
Depends on #668 otherwise requires significant manual work to add the request/response bodies.

What solution would you like?

Iterate on top of #669 so that the "operations to generate" filtering can be removed (or set to *) so that eventual automatic PRs from #667 can add complete new APIs
