Reorder opentelemetry-collector HPA metrics

A current issue between ArgoCD (argoproj/argo-cd#1079) and Kubernetes (kubernetes/kubernetes#74099) makes the HPA stay constantly out of sync. This affects Gitops pipelines when both memory and CPU metrics are used to autoscale the deployment. This change reorders metrics to make sure that they remain in the order that the Kubernetes HPA controller currently expects them to be.
