Deploying Fluentd to test OpsTools in OSP 10 requires the package rubygem-fluent-plugin-elasticsearch if you install the server following https://github.com/centos-opstools/opstools-ansible.

The package was available in OSP 9:

$ sudo yum list rubygem-fluent-plugin-elasticsearch
Loaded plugins: search-disabled-repos
Available Packages
rubygem-fluent-plugin-elasticsearch.noarch                                                       0.7.0-1.el7ost                                                       rhel-7-server-openstack-9-optools-rpms

Not having the package makes the Ansible playbook failing to install the Fluentd server.

The current workaround is adding the OSP 9 opstools repo to the server. If this package is to be required in the GA release to build the Fluentd server then we should have it as part of the repo.
