Remove id field from rbd examples

Currently the RBD examples fail with the following error:

```
kubectl create -f examples/volumes/rbd/rbd-with-secret.json 
error validating "examples/volumes/rbd/rbd-with-secret.json": error validating data: found invalid field id for v1.Pod; if you choose to ignore these errors, turn validation off with --validate=false
```

fixes #28831
