Zerto Local Site Management Example Script

This script demonstrates how to manage and retrieve information about the local Zerto site.

The script performs the following steps:
1. Connects to Zerto Virtual Manager (ZVM)
2. Retrieves local site information
3. Gets site pairing statuses
4. Sends usage data to Zerto
5. Manages login banner settings:
   - Gets current banner configuration
   - Sets a new test banner
   - Verifies the updated settings
   - Disables the banner

Required Arguments:
    --zvm_address: ZVM address
    --client_id: Keycloak client ID
    --client_secret: Keycloak client secret

Optional Arguments:
    --ignore_ssl: Ignore SSL certificate verification

Example Usage:
    python examples/localsite_example.py \
        --zvm_address <zvm_address> \
        --client_id <client_id> \
        --client_secret <client_secret> \
        --ignore_ssl
