Tag EKS cluster security group, route tables, network interfaces and ACLs

[bianchi2]

Primary cluster security group is created by AWS, as a result no additional tags are propagated to it.

Also, some AWS resources that aren't created by Terraform lack tags:

• route tables
• network ACLs
• network interfaces

Tagging them in Terraform module is tricky because we can't use for_each for computed recourses. Instead, we gather the list of ids and tag them after the deployment is finished. We need to do that after deployment also because some resources like network interfaces are created when a new node is created, i.e. during scale up.
