bug: Terraform destroy times out due to orphaned ENI #5

Expected Behavior

Running terraform destroy should remove all infrastructure

Actual Behavior

ENIs can be left dangling due to this issue:

aws/amazon-vpc-cni-k8s#1223

This prevents one or more subnets from being deleted and the Terraform process times out.

Steps to Reproduce the Problem

This only occurs intermittently and is difficult to reproduce on purpose.

This seems to have been mostly mitigated by:

  1. Implementing phased Terraform destroy as recommended by Blueprints team
  2. Leveraging prefix delegation mode in the VPC CNI

Between changes above and sweeper functionality this is not happening, closing for now.
