Patch for v17.20.0

[schwichti]

Hi, I am using an older version, i.e. 17.20.0 of this module. Currently, updating the module would take to long and I need a short-term patch to restrict the security group rule workers_ingress_self which "Allow node to communicate with each other.": see https://github.com/terraform-aws-modules/terraform-aws-eks/blob/v17.20.0/workers.tf#L399

What is the purpose of the rule? Why is it so permissive?

[schwichti]

Are these the security group rules that are currently used in the latest release https://github.com/terraform-aws-modules/terraform-aws-eks/blob/58285f37d1dfaacbf99055ed87f1be19cc39f5ad/node_groups.tf#L61 ? Is it possible to manually recreating such a security group and pass it to the module in version 17.20.0 via the variable worker_security_group_id ?

We won't be releasing any additional changes for v17.x which was deprecated almost a year ago now

I want to patch it myself, but I would need guidance. The rule currently allows all protocols on all ports. I do not know how to restrict traffic without breaking anything.
