This adds the following new packages: + elasticsearch7 + elasticsearch7-oss + logstash7 + logstash7-oss + kibana7 + kibana7-oss + filebeat7 + heartbeat7 + metricbeat7 + packetbeat7 + journalbeat7 The default major version of the ELK stack stays at 6. We should probably set it to 7 in a next commit.
