Summary: The diff introduces support for the creation and deletion of DR config using the k8s operator. It also introduces support to update the list of databases under replication using the operator.
Test Plan:
- Deploy k8s operator using devspace
- Create the CR and ensure that the DR config is crated
```
apiVersion: operator.yugabyte.io/v1alpha1
kind: DrConfig
metadata:
name: prod-to-dr-config
namespace: spothuraju
spec:
name: prod-to-dr-config
sourceUniverse: dr-source
targetUniverse: target
databases:
- "db1"
storageConfig: trial-backup-config
```
- Update the databases and check whether the databases under replication in the DR get updated
- Delete the DR and check whether the DR config gets deleted
