870: fix(topology): remove the internal labels while displaying r=sinhaashish a=sinhaashish

This OPr removes the internal label while labeling a pool

The develop code was like 
```
$ ./target/debug/kubectl-mayastor label pool pool-on-node-one A=B -n openebs
Pool pool-on-node-one labelled successfully. Current labels: {"A": "B", "openebs.io/created-by": "operator-diskpool"}
```

After this PR 

```
$ ./target/debug/kubectl-mayastor label pool pool-on-node-one C=D -n openebs
Pool pool-on-node-one labelled successfully. Current labels: {"C": "D", "A": "B"}
```
