1. contrib/kind: set custom DNS resolver for Kind nodes …

   We are using our Kind provisioning script to create K8s clusters when testing
   in the CI. Recently, we discovered that on some kernels a default DNS resolver,
   which is dockerd, is troublesome for the BPF host routing, which we want to
   test in the CI (#23283).
   
   Fix this by patching the coredns configmap after creating a kind cluster to
   point to the 8.8.8.8 resolver. Alternative fixes (may still be applied later):
   
     * Pass a custom /etc/resolv.conf to kubelet via --resolv-conf in the Kind /
       kubeadm config.
   
     * Override /etc/resolv.conf of Kind nodes after creating a cluster (no race
       condition, as CoreDNS pods won't be started, as a CNI is not ready).
   
     * Patch Kind to allow users to specify custom DNS entries (i.e., docker run
       --dns="1.1.1.1,8.8.8.8").
   
   Fixes: #23283
   Fixes: #23330

2. gh/workflows: re-enable masqueranding for EGW …

   The #23283 should have been fixed by the 3e8f697 ("contrib/kind: set custom
   DNS resolver for Kind nodes") commit, so we can re-enable masquerading by
   default and re-enable fast routing.
