Steps to Reproduce

1. terraform apply to create resources
2. terrafrom destroy to cleanup resources

Important Factoids

References

• I believe this issue is because Pulsar requires to remove the replication configurations on tenant, namespace first then allow to delete this resource.
• So for the terraform provider should check the replication configuration first before the destroy.
