Warning/Notification on cluster status after major upgrade to update logging component

What is the problem that your customer is facing?

Many customer were unaware the logging component need to be upgraded separately. Even after upgrading the cluster to 4.6, still the logging component continues to run in 4.2 or 4.3.

What is the business impact, if any, if this request will not be made available?

The difference is version is not supported and also causing the issue in logging cluster functionality.
Also upgrading from 4.3 to 4.6 logging component on a updated 4.6 cluster is tedious task.

What are your expectations for this feature

There should be a warning message or notification on cluster status after the cluster upgrade stating the logging component continues to run on older version and yet to be upgraded.
