Fixes #16
## What this PR does?
This PR aims to provide users choices for retain or delete volumes after
deleting CRs. Users can use following configurations to control this behaviour.
```yaml
# ...
spec:
# ...
persistence:
volumeReclaimPolicy: Delete # Or "Retain"
```
## How so?
Basically, I added finalizers to CR for controllers to implement
asynchronous pre-delete hooks. In this pre-delete hook, I cleanup all binded
PVCs and orphaned PVCs as well.
See

to learn the context.
