IMPALA-10733: Fix flaky TestKuduOperations.test_replica_selection
This issue is related to IMPALA-11187, 'test_read_mode' can have
unpredicted results by its nature, it sets the 'kudu_read_mode' to
'READ_LATEST'. The 'test_replica_selection' runs just after
'test_read_mode' and the Kudu tests use the same Impala client, thus
'kudu_read_mode=READ_LATEST' persists.
This commit set 'kudu_read_mode=READ_AT_SNAPSHOT' for
'test_replica_selection'.
Testing:
- Ran 'test_replica_selection'
