[sda-cli] Consistent exit code

[nanjiangshu]

Please describe the feature
As an sda-cli user,
I want the command to return a non-zero exit code (e.g., 1) when there are errors and return 0 when the command runs successfully without any errors,
so that the exit code accurately reflects the outcome of the command execution.

Acceptance criteria

• Go through the code and check if the correct exit codes are used (non zero exit codes only in errors)
• Tests verifying the changes are added
