Problem Description

Since Cortex 3.1.0 cant create the Index by itself (as described here: https://github.com/TheHive-Project/Cortex/issues/305) you have to Manually Create it. This leads to Cortex starting and crashing after trying to access Elasticsearch, Log of Elastic does not show a Access attempt from Cortex as far as i can tell

Steps to Reproduce

1, Install Cortex according to Documentation 2. Install the newest Elasticsearch Version 3. Create Index Manually bc of Bug: https://github.com/TheHive-Project/Cortex/issues/305 4. Start Cortex Service
