support python 3.12

- update start.sh, support installing extra apt package on startup if requirements-apt.txt exists.
- requirements-apt.txt is inspired from requirements.txt in python pip.
  the line starts with '#' will be ignored, so that we can add comment in requirements-apt.txt.
- requirements-apt.txt is rename-able by environment variable 'apt_requirements'.
