Exercise 3: Site Discovery
This script demonstrates how to discover and work with Zerto virtualization sites.

Prerequisites:
1. Install the zvml package in development mode:
   cd /path/to/zvml-python-sdk
   pip install -e .
2. Update prerequisites/config.py with your ZVM details

Your task:
1. List all available virtualization sites
2. Get and display local site information

If you need help, check the solution in the solution directory.
