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.
