Description of problem:
We can create a Ceph filesytem/volume using rook by issuing a mgr volume command,
`ceph fs volume create vol00`. We can then remove it using `ceph fs volume rm vol00`. Since removing a filesystem is a destructive operation (pools/data permanently destroyed), we need added an protection say `ceph fs volume rm vol00 --yes-i-really-mean-it`.



How reproducible: Always


Steps to Reproduce:
1. Setup rook as the Ceph's orchestrator
   https://docs.ceph.com/docs/master/mgr/orchestrator_cli/#configuration
   ```
   ceph mgr module enable rook
   ceph orchestrator set backend rook
   ```
2. Create a filesystem/volume as follows using a ceph client
   ```
   ceph fs volume create vol00
   ```
3. Try removing the volume,
   ```
   ceph fs volume rm vol00
   ```

Actual results:
Volume removal passes


Expected results:
Volume removal should fail. You should need an additional flag `--yes-i-really-mean-it` appended to the command to remove the volume.
```
ceph fs volume rm vol00 --yes-i-really-mean-it
```
