Description

Fixes #126

TODOs

Read the Gruntwork contribution guidelines.

• Update the docs.
• Run the relevant tests successfully, including pre-commit checks.
• Ensure any 3rd party code adheres with our license policy or delete this line if its not applicable.
• Include release notes. If this PR is backward incompatible, include a migration guide.
• Attention Grunts - if this PR adds support for a new resource, ensure the nuke_sandbox and nuke_phxdevops jobs in .circleci/config.yml have been updated with appropriate exclusions (either directly in the job or via the .circleci/nuke_config.yml file) to prevent nuking IAM roles, groups, resources, etc that are important for the test accounts.

Migration Guide

Looks like changes are failing to compile

# github.com/gruntwork-io/cloud-nuke/aws/resources
aws/resources/ec2_placement_group.go:32:16: configObj.EC2PlacementGroups undefined (type config.Config has no field or method EC2PlacementGroups)
aws/resources/ec2_placement_group_types.go:41:19: configObj.EC2PlacementGroups undefined (type config.Config has no field or method EC2PlacementGroups)

[wakeful]

Rebasing should fix the problem
