Refactor certbot plugins install

- Added a script to install every single plugin, used in development and debugging
- Improved certbot plugin install commands
- Adjusted some version for plugins to install properly
- It's noted that some plugins require deps that do not match other plugins,
  however these use cases should be extremely rare
