Gate fix: httpd image, elasticsearch, openstack-exporter

There was a change in the upstream reference httpd image for
apache that changed how modules were built for apache.
This change adds the required fix to accomodate the change.
See isssue here https://github.com/docker-library/httpd/pull/87

The Elasticsearch image tag was updated to accomodate the kernel
versions used in the gate as part of the kernel update playbook
See https://github.com/elastic/elasticsearch/issues/28349#issuecomment-360233779

The openstack-exporter binary was changed to reflect changes made
to the openstack-exporter image
