Updated ELK config files to elk 7.x reference samples, bringing over existing customisation from elk_metrics_6x. Removed deprecated use of --pipeline in elastic_beat_setup/tasks/main.yml, --pipeline is no longer a valid cli argument. Updated logstash-pipelines and removed the dynamic insertion of the date into index names. This function is now done with the new ILM feature in elasticsearch rather than logstash. Installation of each beat creates an ILM policy for that beat and this patch does not change the default policy. It is possible that the default policy will exhaust the available storage and future work needs to be done to address this. The non-beat elements of the logstash pipeline (syslog, collectd and others) are not yet updated to be compatible with ILM. Change-Id: I735b64c2b7b93e23562f35266134a176a00af1b7
