Combine dockerfiles
- Use a single Dockerfile
- Select Python version, framework (TF vs Pytorch), and framework version as build arguments
- Remove installation of ormb
- Advanced feature which we can add if needed
- So far users didn't use it
- It makes the image heavy
- Build images with TF 2.1.0, TF 2.5.0 and PyTorch 1.8.1
- Use Python 3.8 in TF 2.5.0 and PyTorch 1.8.1 images
