Add external-ip support for coturn (#1439)

Browse Source 
Handles the case when users are running Coturn with peers in the same network, and these peers connect to the relay server via private IP addresses (e.g., Oracle cloud), which causes relay candidates to be allocated using private IP addresses. This causes issues with external peers who can't reach these private addresses.

Use the provided IP address with NETBIRD_TURN_EXTERNAL_IP or discover the address via https://jsonip.com API.

For quick-start guide with Zitadel, we only use the discover method with the external API
