Added 5 examples to demostrate GPU aware scheduling features

This adds more examples for GAS. The tests prints the container names
and corresponding GPUs to the logs.

+This folder has simple examples which use kubernetes extended resources and other GAS features.
 
 To deploy, you can run in this folder:
 
 ```
-kubectl apply -f .
+kubectl apply -f <test_file_name>
 ```
 
 Then you can check the GPU devices of the first pod in the deployment with:
 
 ```
-kubectl exec -it deploy/bb-example -- ls /dev/dri
-```
+kubectl exec -it deploy/<deployment name> -- ls /dev/dri
+```
+
+Or you can use logs command to check which GPUs the pod is using:
+
+```
+kubectl logs --all-containders=true <pod name> 
+```
+
+With describe command you can check in which GPUs GAS has scheduled the pods along with the other pod information:
+
+```
+kubectl describe pods <deployment name>
+```
