Prepare elasticsearch structure for Zabbix 5.0

Make sure there is 'your-elasticsearch.here' record in:

grep your-elasticsearch.here /etc/hosts

Observe structure:

curl -X GET http://your-elasticsearch.here:9200/_cat/indices?v

Remove old structure:

curl -X DELETE http://your-elasticsearch.here:9200/str
curl -X DELETE http://your-elasticsearch.here:9200/log
curl -X DELETE http://your-elasticsearch.here:9200/text

Or:

curl -X DELETE http://your-elasticsearch.here:9200/{str,log,text}

curl -X PUT \
 http://your-elasticsearch.here:9200/text \
 -H 'content-type:application/json' \
