Calico CNI

Current top-level still contains the deprecated Canal implementation. Removed once new AWS config is tested and rolled out to all existing clusters.

AWS

Calico is setup based on the upstream calico-vxlan config from
https://docs.projectcalico.org/v3.15/manifests/calico-vxlan.yaml

Changes:

• VxLAN set to Always to not expose cluster communication to VPC

  -> EC2 SecurityGroups still apply and only need to allow UDP 4789 for VxLAN traffic
  -> No need to disable source/destination check on EC2 instances
  -> Prepared for optional WireGuard encryption for all inter node traffic

• MTU set to 8941

• Removed migration init-container

• Disable BGB and BIRD health checks

• Set FELIX log level to warning

• Enable Prometheus metrics
