Added configurable timeouts and retry logic to all curl commands in publicIpFromMetadata():
- --connect-timeout 5: 5 seconds to establish connection
- --max-time ${METADATA_TIMEOUT:-20}: Configurable timeout (default 20 seconds)
- Retry logic: Try up to 2 times with 2-second delay between attempts
- Environment variable: METADATA_TIMEOUT can override default timeout
This prevents the installation script from hanging indefinitely when:
- Metadata services are slow or unresponsive
- Network issues cause connections to stall
- Script is run in non-cloud environments where metadata IPs don't respond
The increased timeout (20s) and retry logic ensure compatibility with:
- Azure deployments in secondary regions (known to be slower)
- High-latency environments (satellite, rural connections)
- Corporate environments with proxies or deep packet inspection
- Temporary network glitches or cloud provider maintenance
The existing fallback to publicIpFromInterface() will handle cases where
metadata endpoints are unavailable after all retry attempts.
