[REQ] Expose all top-level config options as properties

Created by: InfoSec812

Is your feature request related to a problem? Please describe.

Some of the options in the CodeGenMojo are exposed such that you can pass the property on the Maven command-line using -Dopenapi.generator.maven.plugin.<property>, but not all. I propose that ALL of those properties should be exposed and that the documentation should be updated to reflect the property name as well.

Describe the solution you'd like

Modify the CodeGenMojo to include property exposure in all @Parameter annotations

Describe alternatives you've considered

None that I can think of

Additional context

I can submit a PR for this if it is helpful.
