Protect EKS Clusters from Accidental Deletion

Enabling deletion protection safeguards clusters from unintended removal. When enabled, deletion protection must be disabled before the cluster can be deleted. Attempting to delete an active cluster with deletion protection enabled will result in an InvalidRequestException.

To enable deletion protection for an existing cluster (must be in Active status):

`aws eks update-cluster-config \
 --deletion-protection \
 --name <cluster-name> \
 --profile <profile-name> \
 --region <region>`

To disable deletion protection for an existing cluster:

aws eks update-cluster-config \
 --no-deletion-protection \
 --name <cluster-name> \
 --profile <profile-name> \
 --region <region>
