Issue with k8s.io/docs/tutorials/stateful-application/basic-stateful-set/

[IhorHryshkov]

This is a Bug Report
Is not a bug, but I think this is feature.

Problem:
In version 1.15.0 kubernetes does not return error, how writing in documentation:

In a second terminal, recreate the StatefulSet. Note that, unless you deleted the nginx Service ( which you should not have ), you will see an error indicating that the Service already exists.

kubectl apply -f web.yaml
statefulset.apps/web created
Error from server (AlreadyExists): error when creating "web.yaml": services "nginx" already exists

Proposed Solution:
I think need update documentation for 1.15.0 version and add next response if user install 1.15.0 version:

kubectl apply -f web.yaml
service/nginx unchanged
statefulset.apps/web created
