Which issue(s) this PR fixes:
Issue longhorn/longhorn#13438
What this PR does / why we need it:
The Calico CNI plugin works in IP-in-IP mode, i.e. the IP packet is packed into another IP packet and forward to other nodes. However, AWS EC2 checks the source & destination, and drops such packets due to security concern. This PR allows such traffic for such CNI setup.
