Enhancements to the native mode installer for a streamlined standalone experience

[s-akhtar-baig]

The existing installer helps deploy required services to run the InstructLab UI on a local machine in the native mode. However, there are potential areas of improvement to bring a more streamlined installer to the end users:

• Improve documentation
  • Add video(s) showing the output from a terminal in a step-by-step manner
• Display the configuration values used by the installer
• Provide an interactive mode which will allow users to override the default values
• Check if running in a python virtual environment
  • If not, then setup a new virtual environment
• Auto-detect ilab installation
  • If none found, then install and configure ilab
