Bug 1519679

Description of problem:

logging-fluentd not using output-ops-extra-localfile.conf after update from v3.6.173.0.21 to v3.6.173.0.49. The logs where not written to the file inside the fluentd pod.

Version-Release number of selected component (if applicable):

-OCP v3.6
-RHEL 7.4

How reproducible:


Steps to Reproduce:
1. Depoly the logging project using ansible playbook files.
2. Initially do not use the variables 'openshift_logging_es_ops_host=logging-es-ops','openshift_logging_use_ops=true' in the inventory file
3. Once deployed check the environment variable value ES_HOST and OPS_HOST, both has the same value.

Actual results:

Due to same value the fluentd-ops file is not getting created inside the fluentd pod.

$ oc rsh logging-fluentd-jvt5h
sh-4.2# ls -ltr /var/fluentd-out/
total 3584
-rw-r--r--. 1 root root 1710120 Nov 29 13:25 fluentd.20171129.b55f1e3152b0f0b44

Expected results:

Both the files must get created inside the fluentd pod.

sh-4.2# ls -l /var/fluentd-out/
total 1792
-rw-r--r--.  1 root root 957428 Nov 29 03:43 fluentd-ops.20171129.b55f1b0aabe17a1c6
