IMPALA-7864: (Addendum) Deflake test_replan_limit by postponing catalog fetches
TestLocalCatalogRetries.test_replan_limit runs REFRESH and SELECT
queries concurrently on a table, and expects one of the query hits
inconsistent metadata.
This patch increases the chance of inconsistent metadata by injecting
a latency (500ms) before each catalog fetch. So it's more likely that a
request is fetching stale metadata. Also bump up the timeout of
thread.join() so we can try out all the attempts.
Test
- Run test_replan_limit 1000 times without any error.
- Run all tests of TestLocalCatalogRetries 100 times without any error.
