fix curator

-the old curator does not support ES 5.x
-include curator 5.1.1 and pin version to exactly that to avoid surprises with disruptive updates
-configs reside in /etc/tpot/curator
-will be started daily through /etc/crontab
-by default all logstash indices older than 90 days will be deleted
