Description

aswinshakil and I noticed that we SCM is shutdown normally it prints out the ERROR log:

2022-06-21 20:37:52,246 ERROR org.apache.hadoop.hdds.scm.server.StorageContainerManager: Terminating with exit status 1: scm statemachine is closed by ratis, terminate SCM

1. This can be misleading as it shouldn't print ERROR if SCM is being shut down normally;
2. And the exit code should be 0 if shutdown is successful. >0 values conventionally indicates errors.
