Delete the federation namespace from fcp instead of individual objects

**What this PR does / why we need it**:
This PR simplifies cleanup by deleting the entire namespace instead of individual objects.
This PR is linked to https://github.com/kubernetes/kubernetes/issues/50543. This may not solve the issue but instead to try an alternative.

**Release note**:
```release-note
NONE
```
