Description of problem:
After deploying logging 3.4.1 successfully by using deployer pod and then upgrade to logging 3.5.0 via ansible, the upgrade is failed due to take the wrong namespace. In this defect, my namespace is juzhao, but ansible take "/tmp/openshift-logging-ansible-x00dCB/admin.kubeconfig" as namespace


Version-Release number of selected component (if applicable):
# openshift version
openshift v3.5.0.18+9a5d1aa
kubernetes v1.5.2+43a9be4
etcd 3.1.0


Image id:
openshift3/logging-elasticsearch    d715f4d34ad4
openshift3/logging-kibana    e0ab09c2cbeb
openshift3/logging-fluentd    47057624ecab
openshift3/logging-auth-proxy    139f7943475e
openshift3/logging-curator    7f034fdf7702

How reproducible:
Always


Steps to Reproduce:
1. Deploy logging 3.4.1 first, make sure all the pods are running
and kibana UI can be accessed.

2. prepare the inventory file

[oo_first_master]
$master-public-dns ansible_user=root ansible_ssh_user=root ansible_ssh_private_key_file="~/cfile/libra.pem" openshift_public_hostname=$master-public-dns

[oo_first_master:vars]
deployment_type=openshift-enterprise
openshift_release=v3.5.0
openshift_logging_install_logging=false
openshift_logging_upgrade_logging=true

openshift_logging_kibana_hostname=kibana.$sub-domain
public_master_url=https://$master-public-dns:8443
openshift_logging_fluentd_hosts=$node

openshift_logging_image_prefix=registry.ops.openshift.com/openshift3/
openshift_logging_image_version=3.5.0

openshift_logging_namespace=juzhao
openshift_logging_use_ops=true
openshift_logging_es_cluster_size=1

3. Running the playbook from a control machine (my laptop) which is not oo_master:
git clone https://github.com/openshift/openshift-ansible
ansible-playbook -vvv -i ~/inventory   playbooks/common/openshift-cluster/openshift_logging.yml
