[Bug-fix] Update correct data partition of fragment which contains Repeat Node

[EmmyMiao87]

Proposed changes

The Repeat Node will change the data partition of fragment
when the origin data partition of fragment is HashPartition.
The Repeat Node will generate some new rows.
The distribution of these new rows is completely inconsistent with the original data distribution,
their distribution is RANDOM.

If the data distribution is not corrected,
an error will occur when the agg node determines whether to perform colocate.
Wrong data distribution will cause the agg node to think that agg can be colocated,
leading to wrong results.
For example, the following query can not be colocated although the distributed column of table is k1:

SELECT k1, k2, SUM( k3 )
FROM table
GROUP BY GROUPING SETS ( (k1, k2), (k1), (k2), ( ) )
