Merged HEAD-BUG-FIX (5.0/Cloud) to HEAD (4.3/Cloud)

73348: Merged V4.2-BUG-FIX (4.2.3) to HEAD-BUG-FIX (4.3/Cloud)
      73162: Merged V4.1-BUG-FIX (4.1.10) to V4.2-BUG-FIX (4.2.3)
         73054: Added LockDAO.releaseLockQuiet and used it for the callback's precautionary lock release
          - Fixes MNT-11507: JobLockService automatic refresh is triggering a retry under normal conditions
          - Prevents a DEBUG message from RetryingTransactionInterceptor when the normal condition is for
            the lock to no longer exist
