What changes were proposed in this pull request?
Backport HIVE-22453. Describe table unnecessarily fetches partitions
Why are the changes needed?
When users have highly partitioned table (10k+), all describe commands will take a very long time to complete. This change will make it such that only "describe extended/formatted table" will start gathering partition statistics.
Does this PR introduce any user-facing change?
No
How was this patch tested?
Manual testing.
