db_stress: sometimes call CancelAllBackgroundWork() and Close() before closing DB (#6141)

Browse Source 
Summary:
CancelAllBackgroundWork() and Close() are frequently used features but we don't cover it in stress test. Simply execute them before closing the DB with 1/2 chance.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6141

Test Plan: Run "db_stress".
