This uses aws-nuke and awslimitchecker to monitor the new vault CI account to clean up and prevent resource quota exhaustion. AWS-nuke will scan all regions of the accounts for lingering resources enos/terraform didn't clean up, and if they don't match exclusion criteria, delete them every night. By default, we exclude corp-sec created resources, our own CI resources, and when possible, anything created within the past 72 hours. Because this account is dedicated to CI, users should not expect resources to persist beyond this without additional configuration.
