Create questions for another user

Hello everyone. This is my first issue in this project.

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

We use a cloud-hosted Answer instance. It's common that some possible users do not even know the app and use another channel to ask something, like an issue in a project, for example, or just think something is a bug while it's not. We need a quick way to do a soft move, without forcing the user to rewrite everything.

## Describe the solution you'd like

I think best experience for user would be having an admin endpoint to create the question as another user. So we can use it in workflows. It's already possible to have a user to create the question using the API, but it should be the asking user because he'll choose the right answer.

## Describe alternatives you've considered

A simpler feature may be fill the new question form with query parameters, like "http://my-instance/questions/ask?title=Test%20Title&description=My%20%test%description&tags=mytag1,mytag2. This is a good feature in GitLab and GitHub while opening issues.

I can work in the solution if needed.

No se nombran archivos ni pruebas. Empieza revisando la API existente de creación de preguntas y la ruta de autorización para las acciones de administrador; se consideraría terminado con un alcance definido y pruebas que cubran el workflow elegido, incluido quién puede crear una pregunta para otro usuario.
