- Fix bug in python requests module missing after delete py3-pip from build stage
- Downgrade the requirement of bcrypt to >=3.1.7 for older python3 version compatibility
- avoid running gunicorn as root user
- use setcap to allow gunicorn starting with a privileged port
- write permission only on /app/configs folder
- su command removed from entrypoint.sh, because it runs as pda user
This allows for easy setup with no extra configuration.
Also update docs to reflect the new and easy way to run PowerDNS-Admin.
