IMPALA-13453: Avoid reloading partition if it is unchanged
In table level REFRESH, we check whether the partition is actually
changed and skip updating unchanged partitions in catalog. However, in
partition REFRESH, we always drop and add the partition. This leads to
unecessarily dropping the partition metadata, column statistics and
adding them back again. This patch adds a check to verify if the
partition really changed before reloading the partition to avoid
unnecessary drop-add sequence.
