Fixed ZooKeeper service usage to delete /controller znode on migration rollback #10373

Type of change

  • Bugfix

Description

This PR fixes #10371.
The current code, to get the ZooKeeper connection string from the service in order to connect to ZooKeeper and delete the /controller znode during KRaft migration rollback, doesn't take into account the full name (i.e. including namespace), so the operator can't connect when the cluster is running in a different namespace.
The PR fixes it.
