Subject: [PATCH] fix: Open udp port 53 on master to support CoreDNS

In Icc4aa1f61f3b3937e5d9cc35dbe01c63c18ba3cd, we only opened tcp port 53
but services running on workers are unable to talk to CoreDNS service
running on master nodes when using Calico v3.13.1 without also opening
udp port 53. This patch addresses this issue.
