Ingress resources are not getting deleted even though the alb ingress controller deployment is deleted

Reference: [https://github.com/kubernetes-sigs/aws-load-balancer-controller/issues/1629#issuecomment-726872539]

I deleted the AWS Load Balancer Controller (alb) before deleting the ingress, and I couldn't delete the ingress.

Solution:
-> % k get ingress echoserver   -o yaml | grep -A 5 finalizers
finalizers:
- group.ingress.k8s.aws/mygroup
generation: 19
name: echoserver
namespace: default
resourceVersion: "5730914"

-> % kubectl patch ingress echoserver -p '{"metadata":{"finalizers":[]}}' --type=merge
ingress.networking.k8s.io/echoserver patched

#kubectl patch pod example-pod -p '{"metadata: {"finalizers": null}}'


and now it's gone!
