Make a single YAML for easy exporter-only deploy

+# Exporter Deployment
+
+This is the one YAML file that is the aggregation of the regular deployment files. This is done for easy distribution, allowing users to `kubectl apply` an exporter-only deployment without cloning the whole repository. Apply on the parent directory won't apply anything in this directory unless `kubectl apply --recursive=True` is used.
+
+## Usage
+
+Please be aware, you will have to change both the `Namespace` and `ClusterRoleBinding` resource if you want to deploy to a namespace other than `cost-model`.
+
+``` sh
+kubectl apply -f exporter.yaml --namespace cost-model
+```
