Convert deploy-virtual-machines.sh to Python with VM recreation control

[bruj0]

This PR converts the existing Bash script deploy-virtual-machines.sh to a Python implementation with added functionality to control VM recreation.

Changes

• Converted the entire Bash script to an equivalent Python implementation
• Added a command-line parameter --no-recreate to disable recreating existing VMs
• Maintained all original functionality including:
  • System compatibility checks
  • Memory-based VM specification adjustments
  • VM deployment and provisioning
  • Host entry configuration
  • Script transfers to VMs

Usage

The script can be run with:

# To recreate VMs (default behavior):
python3 deploy-virtual-machines.py

# To keep existing VMs (new functionality):
python3 deploy-virtual-machines.py --no-recreate

Benefits

• Better structured code with functions and proper error handling
• More robust parameter handling through argparse
• Easier maintenance and future extension
• Keeps existing VMs when desired, saving time during development
