IMPALA-14718: Fix flaky test test_confirm_individual_refresh
The flakiness was introduced by 'test_table_repair': it executed a
global INVALIDATE METADATA that affected other tests running in
parallel.
'test_confirm_individual_refresh' failed because it was running
in parallel with 'test_iceberg.py::test_table_repair', which ran
an INVALIDATE METADATA exactly before a SELECT query of
'test_confirm_individual_refresh', which was checking that data in
its table is not reloaded. Due to the global invalidate, the data
was reloaded anyway.
Fix: instead of global INVALIDATE METADATA, 'test_table_repair'
only invalidates its own table now.
