* refactor: update global context STUN server initialization
Modified global context initialization to use a single StunInfoCollector
instance with properly configured IPv4 and IPv6 servers instead of
creating separate instances.
feat: add IPv6 STUN server configuration support
Added interface methods and config struct fields to support both IPv4
and IPv6 STUN server configuration. Modified getter and setter methods
to handle Option<Vec<String>> type for both server types.
feat: enhance StunInfoCollector with IPv6 support
Updated StunInfoCollector to support both IPv4 and IPv6 STUN servers.
Added new constructor that accepts both server types and methods to set
them independently.
feat: add CLI argument for IPv6 STUN servers
Added command line argument support for configuring IPv6 STUN servers.
Updated configuration setup to handle both IPv4 and IPv6 STUN server
settings.
docs: add localization for STUN server configuration
Added English and Chinese localization strings for the new STUN server
configuration options, including both IPv4 and IPv6 variants.
This patch implements:
1. A dns server that handles .et.net. zone in local and forward all other queries to system dns server.
2. A dns server instance which is a singleton in one machine, using one specific tcp port to be exclusive with each other. this instance is responsible for config system dns and run the dns server to handle dns queries.
3. A dns client instance that all easytier instance will run one, this instance will try to connect to dns server instance, and update the dns record in the dns server instance.
this pr only implements the system config for windows. linux & mac will do later.
