`az storage blob directory` failures return exit code 0

When running a az storage blob directory command which results in a failure, the exit code of the command is 0, meaning it was successful, not 1, which it should be on failure.

I’ve tried this on 2 commands: Uploading a file:

[user@localhost ~]$ az storage blob directory upload --account-name mystorageacct --container mycontainer --destination-path / --source testfile
INFO: Scanning...
INFO: Any empty folders will not be processed, because source and/or destination doesn't have full folder support
