The feature flags test util is offering some functions to retrieve the status of feature flags in sharded clusters.
Purpose of this ticket is to make the library resilient to failovers since we've been observing some [rare] failures in suites with stepdowns and primary nodes termination.
Examples of errors hit during testing:
