Installing elasticsearch 6.x fails as /etc/elasticsearch/jvm.options.d does not exist

[midgleyc]

Being able to configure JVM options using jvm.options.d only starts working in elasticsearch 7.x, and an install of 6.x fails as this directory does not exist:

(item=/etc/elasticsearch/jvm.options.d/heap.options) => {"ansible_loop_var": "item", "changed": false, "checksum": "34a473b4557de33ad88f13c4ef2289c329071077", "item": "/etc/elasticsearch/jvm.options.d/heap.options", "msg": "Destination directory /etc/elasticsearch/jvm.options.d does not exist"}
