Resource tags cannot be modified after creation when aws-load-balancer-type is set to "nlb"

[vjanelle]

Is your feature request related to a problem?
When attempting to update resource tags on existing load balancers, we are unable to mutate the values.

Debugging this with AWS, we determined that if the service.beta.kubernetes.io/aws-load-balancer-type value isn't set to external or nlb-ip, the load balancer controller will ignore the request. The in-tree service controller I think would modify the values, but it is passing all responsibility over to the aws-load-balancer-controller.

Describe the solution you'd like
When modifying resource tags with the aws-load-balancer-type set to nlb, the resource tags are updated, without having to recreate the nlbs.

Describe alternatives you've considered
We've considered modifying the aws-load-balancer-type to 'nlb-ip', but the documentation says this would lead to a resource leak.

Thank you for bringing this to our attention. We are currently attempting to reproduce this issue on our end. /kind/feature

Thanks - a key thing is that the additional tags annotation has to be mutated after being set the first time. It'll work once, basically.
