ansible task log

Description of problem:
Currently ansible didn't set value to parameter "use_journal" while deploy logging, and fluentd collects logs from json-file log driver by default:
$ oc logs -f logging-deployer-dlnow
...
+ use_journal=
+ journal_read_from_head=false
+ journal_source=
...

We should enable ansible to deploy logging with the default journald log driver.

Version-Release number of selected component (if applicable):
# openshift version
openshift v3.4.0.32+d349492
kubernetes v1.4.0+776c994
etcd 3.1.0-rc.0

openshift-ansible-3.4.31-1.git.0.4b78e57      


How reproducible:
Always

Steps to Reproduce:
1. Deploy logging with these parameters passing to ansible:
 openshift_hosted_logging_deployer_prefix: ${ops-registry-image-prefix}
 openshift_hosted_logging_deploy: true
 openshift_hosted_logging_storage_kind: dynamic
 openshift_hosted_logging_deployer_version: 3.4.0

2. Check logging pods:
# oc get po
NAME                          READY     STATUS      RESTARTS   AGE
logging-curator-1-l0fzh       1/1       Running     0          4h
logging-deployer-dlnow        0/1       Completed   0          4h
logging-es-1yl4qhyc-1-91pkd   1/1       Running     0          4h
logging-fluentd-5f3s1         1/1       Running     0          4h
logging-fluentd-dhojf         1/1       Running     0          4h
logging-kibana-1-tz7ks        2/2       Running     0          4h

3. Check deployer configmap content
# oc get configmap logging-deployer -o yaml
apiVersion: v1
data:
  es-cluster-size: "1"
  es-ops-cluster-size: "1"
  es-ops-pvc-dynamic: "true"
  es-ops-pvc-prefix: logging-es
  es-ops-pvc-size: 10Gi
  es-pvc-dynamic: "true"
  es-pvc-prefix: logging-es
  es-pvc-size: 10Gi
  kibana-hostname: kibana.{subdomain}
  kibana-ops-hostname: kibana-ops.{subdomain}
  public-master-url: https://{master-domain}:8443
kind: ConfigMap
metadata:
  creationTimestamp: 2016-12-05T02:12:33Z
  name: logging-deployer
  namespace: logging
  resourceVersion: "1221"
  selfLink: /api/v1/namespaces/logging/configmaps/logging-deployer
  uid: 4865c5ef-ba90-11e6-9243-42010af00014

4. Check the fluentd log driver

Actual results:
4. Fluentd collects logs from json-file log driver since "use_journal" was set to empty

Expected results:
4. Ansible should be enabled to deploy logging with the default journald log driver

1. ansible log attached
2. deployer pod log attached
