2021-03-04cnat: Add calico/k8s src policyNathan Skrzypczak1-0/+3
This patch implements k8s-specific extensions to the cnat plugin. This could be done by exposing a richer semantic on srcNAT policies, but this might be too complex work at this point. Also k8s fits quite well as a 'cloud NAT' usecase.
