This change reduces code throughout the playbooks thereby speeding up
the task execution.
* A new role named `elastic_beat_setup` was created to
facilitate template setup as needed.
* Beats retention policies are now defined on the elastic-logstash
nodes instead of on all target hosts. This method will speed-up
deployments on massive installations while streamlining all deployments.
* Kibana variable assumptions have been fixed. This will allow for
deployments without Kibana to be accomplished.
