Feature Summary

For an operator to see the status of NVSentinel flags, they have to dig through confimaps and hence it is also not easy to get a fleet wide view of the status of feature flags. For an operator managing 100s of clusters it is important to have a dashboard showing the status of feature flags.

Problem/Use Case

Enable an operator managing 100s of clusters to create a dashboard that can be used to track the status of feature flags.

Proposed Solution
