) In elastic#55763 I thought I could remove the flag that marks reindexing was finished on a data frame analytics task. However, that exposed a race condition. It is possible that between updating reindexing progress to 100 because we have called `DataFrameAnalyticsManager.startAnalytics()` and a call to the _stats API which updates reindexing progress via the method `DataFrameAnalyticsTask.updateReindexTaskProgress()` we end up overwriting the 100 with a lower progress value. This commit fixes this issue by bringing back the help of a `isReindexingFinished` flag as it was prior to elastic#55763. Closes elastic#56128 Backport of elastic#56135
