[przemyslavic]

✔️ epicli apply: AWS/Azure x Ubuntu/RHEL/CentOS with elasticsearch-curator enabled in feature-mapping.

[to-bar]

✔️ epicli upgrade: AWS/RHEL on v0.8.2 cluster with elasticsearch_curator added to inventory and manually installed older version of Curator (5.8.1) before running the upgrade.
