Instance binding cannot be deleted successfully

[yqf3139]

When I delete the binding, it seems the binding is deleted and the secrets are also deleted.
But creating the binding again will lead to an error:

Error from server (AlreadyExists): error when creating "examples/mariadb-binding.yaml": object is being deleted: bindings "mariadb-binding" already exists

Is this a bug or service-catalog?

What are the steps you went through? It's been a while since I touched this so I'll need to try and reproduce.

I follow the steps in this repo on a google container engine instance. I used the service catalog with etcd backend.
Everything works well. And I run kubectl --context service-catalog delete -f examples/mariadb-binding.yaml, it said the binding is deleted. When I recreate the binding, the error happened.
