UI log should contains information related to upgrade of nodes

after upgrade from 1.8.* to 2.0 UI console doesn't contains any information that node was upgrade.
This information would be very useful for user to identify issues or for upgrade of large clusters

UI logs example after upgrade 2 nodes in cluster with 3 buckets:
