IMPALA-14651: Fix flaky test_loaded_tables_metric due to report delay
test_loaded_tables_metric() added in IMPALA-13863 was failing
intermittently because it didn't account for the random delay in
ImpaladTableUsageTracker's table usage reporting.
The tracker sleeps for [0.5, 1.5) * REPORT_INTERVAL_MS (5-15s) before
sending usage reports to catalogd, after which the TTL countdown
begins.
The test was waiting for timeout * 2, but the actual max time is:
- Invalidation TTL: timeout
- Report delay: up to 15s (1.5 * 10s REPORT_INTERVAL_MS)
- Metric update + RPC/serde buffer: ~2s
Changed the wait timeout from (timeout * 2) to (timeout + 17) to properly
account for the maximum report delay plus TTL and metric update.
