Christian Berendt 83bda89600 Increase vm.max_map_count on elasticsearch nodes
When using newer Elasticsearch versions you will receive the following error
when trying to start: elasticsearch | max virtual memory areas
vm.max_map_count [65530] likely too low, increase to at least [262144]

This could be solved by increasing the vm.max_map_count value via sysctl.

Reference: https://www.elastic.co/guide/en/elasticsearch/reference/current/vm-max-map-count.html
