This reverts the changes made to Elasticsearch, Kibana and fluent
logging charts in https://review.openstack.org/#/c/550229/7.
Specifically, this moves the images back to previous used versions
and makes the required changes to the fluent-logging elasticsearch
template job to include the correct mapping directives for the
elasticsearch template.
This change was made to give more time for evaluating a more
robust solution for switching to the official upstream images that
will not cause intermittent gate failures as seen since 550229 was
merged
