[REQ] Controller interface naming

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

When generating server code with the maven plugin, the controller interface classe names are generated base on the name of the API endpoints from the first "/" until the second "/", if any.
I would like to be able to set custom names for the interface names.

Describe the solution you'd like

If I have 3 API endpints:
/car/paint
/car/wash
/moto
/truck/paint

This will generate 3 controller interfaces: CarApi, MotoApi, TruckApi.

I would like that all of the endpoint to be generated under the same controller interface, for example, MyAppApi.

Describe alternatives you've considered

I tried to look into the plugin configuration and I didn't find a way to do it.
One easy way how thi could be implemented is based on tags that we give to each API endpoint. In this case I would give to all the API endpoint the tag "MyApp".

Additional context

Nothing to add.

Start with the Maven plugin's server-code generation path and trace how controller interface names are derived from API endpoint paths. Check the plugin configuration and endpoint tag handling described in the issue. Done means a configurable naming approach can generate all listed endpoints under one interface such as MyAppApi.
