+##########################################
+# This script is used to destroy any
+# leftover resources in the case where
+# a GitHub actions workflow is cancelled. 
+# There is a chance that this will fail due to
+# the eks fargate and adot operator tests requiring 
+# options to pass in. This is a best effort to clean up
+# as many resources as possible though and any type
+# of cleanup is better than cancelling with no cleanup. 
+#
+#
+# Inputs
+# $1: aws_service
+# $2: testcase 
+# $3: ECS/EC2 only - ami/ecs launch type 
+# $3: For EKS-arm64 we expect region|clustername|amp_endoint
