Steps

1. Init - Load config.json
2. Create TUN device
3. Create route for 100.64.0.0 network to TUN
4. Initialize DNS service
5. Load identity
6. Initialize logging
7. Connect to controller
8. Download network configuration
9. Initialize Channels to Edge Routers
10. Initialize Services
    1. Insert DNS names
    2. Create routes for IPs to 100.64.0.0 block
11. Collect latency information for ER selection
12. Complete DNS initialization with Service names
13. Periodically check for updates to services or other network config. Polling controlled by app, including desktop edges and tunnelers, 10 or 15 seconds in OpenZiti released software.
14. Update services, add or delete Edge Routers, etc. as necessary.
