Subject: [PATCH 1/2] Update IndexOptimize.sql

Included lock timeout setting on fetching details about indexes/statistics. Even with the transaction level to readuncommitted, I had an issue on my environment that locked this query for 15 hours because of another process taking that long (an issue on its own :) ).
