We currently use `StateTransferInProgressException` as a marker that a write command failed to acquire the state transfer lock and it should be retried. With ISPN-1704 I added another exception, StateTransferLockReacquisitionException, to signal that a write command failed to re-acquire the state transfer lock after it had already acquired it.

These exceptions often appear in the logs and confuse users (see ISPN-1610), so it would be best to use special return values. We may also need a flag in the InvocationContext for StateTransferLockReacquisitionException.
