Add Domain Aware Style Transfer API project

[alexandergg]

Principal features:

1. Add a Domain Aware Style Transfer API scaffolding project using the FastAPI library.
2. Add API endpoints to support the developed models (vanilla, adversarial loss) and the interpolation case.
3. Create configurations files (.json) for each model inference and baseline process.
4. Refactor and re-structure the code. Remove unnecessary dependencies, clean the code and modify the code to avoid GPU out of memory during inference process.
5. Add a Docker configuration (Dockerfile) and environment.yml to execute locally (cmd or Docker) or execute the project in the cloud using Container Instances with GPU.
6. Add README.md as a user guide to install dependencies locally or deploy the API in an Azure Container Instance using Azure Portal.
