Beta Branch add python_alternatives_setup function for EL8+ in 130.00beta01

add python_alternatives_setup function for EL8+ in 130.00beta01

---

- for EL8+ OSes like AlmaLinux 8 or Rocky Linux 8, allow Centmin Mod to install Python out of the box if end user wants to via persistent config /etc/centminmod/custom_config.inc variable PYTHON_INSTALL_ALTERNATIVES='y' that can be set before initial Centmin Mod installation. Or after initial install the same set persistent config variable will install Python 3.6 and setup python binary unversioned reference to default to python3 and set pip to pip3 mapping when you next run centmin.sh menu.
- EL8+ no longer set unversioned python and pip commands unless you configure it to map pip to pip3 and python to python3 which is what this update allows EL8+ installs to do so.
- Centmin Mod defaults PYTHON_INSTALL_ALTERNATIVES='n' to disable this unless end user chooses via persistent config /etc/centminmod/custom_config.inc variable PYTHON_INSTALL_ALTERNATIVES='y'
