that is used to contain resource sync state, account ownership,
constructed ARN for the resource
ackResourceMetadata.arn
Optional		string
ARN is the Amazon Resource Name for the resource. This is a
globally-unique identifier and is set only by the ACK service controller
once the controller has orchestrated the creation of the resource OR
when it has verified that an “adopted” resource (a resource where the
ARN annotation was set by the Kubernetes user on the CR) exists and
matches the supplied CR’s Spec field values.
