Add customized config to skip finalizers.

[realAaronWu]

Description

Zookeepercluster has mandatory finalizers in order to delete pvcs when deleting the pods. This should be fine if we always delete Zookeepercluster pods before deleting the operators. This can be done by injecting a helm pre-delete hook. But on VS7 env, they forbid calling helm hooks, and VS terminates the namespace which kills all pods/secrets/configmaps at once without ordering, so deadlock can happen if operators are killed first before the Zookeepercluster pods. Add this config flag to skip adding finalizers to Zookeepercluster to avoid this situation.
