Add scripts for managing VM and LXC container power states and fan control
- Implemented set_fanspeed.py for dynamic fan speed control based on temperature. - Created ilo_poweroff.py and ilo_poweron.py for iLO power management. - Added ipmi_poweroff.py and ipmi_poweron.py for IPMI power control. - Developed vm_start.py, vm_stop.py, vm_restart.py, and vm_shutdown.py for VM and LXC management. - Introduced wrapper scripts (start_wrapper.sh, stop_wrapper.sh) for simplified execution. - Removed deprecated shell scripts for power control.
