Description

The fix for IMPALA-9887 speeds up ASAN builds by adding the ability to shard EE tests and restart Impala between them. When EE_TEST_SHARDS is set, each restart of Impala will generate new INFO, ERROR, WARNING glogs. Unfortunately, the max_log_files is set to 10 by default, so the older logs will be deleted to make way for the new logs.

We should change it to a higher value to keep all of the logs when using EE_TEST_SHARDS. This is something that we already do for custom cluster tests.
