docker: improve image layout and backend-only/frontend-only images

[nicoloboschi]

Changes:

• Improved official image
  • Added runtime layer to keep only the virtual environement without source code
  • Reproducible build by removing poetry lock in the docker image
  • Added opencontainers labels
  • Add test on CI to verify build is working with correct version of langflow
• Added a new official image langflow-ai/langflow-backend meant to be ran as backend-only
  • Start from the official image
  • Remove the frontend directory (improve size and reduce vulnerability surface)
  • Run with backend-only by default
• Added a new official image langflow-ai/langflow-frontend meant to be ran as frontend-only
  • Uses nginx debian official image
  • Build NPM and copy the build files into the nginx directory
  • Backend url must be provided at runtime via env or via first arg (env BACKEND_URL)
  • Nginx rule to bypass everything starting with /api to that backend url
