Make elasticsearch persistent

[JCombee]

At the moment the data in elastic search gets perged when you destroy the container. I think the elastic search containers should also have a persistent volume just like mysql. This will prevent that you have to reindex magento projects every time you remove the containers.

Ive looked up what the actual directory is that you need to persist: /usr/share/elasticsearch/data.
