Return non-zero exit code if test failed

[popcornylu]

Summary

Currently, when there are failed test, it still return zero exit-code.

If we would like to integrate pipeline in workflow system (e.g. airflow) or CI system (e.g. jenkins, github action), it would be better to failed with non-zero exit code so that we can make the job with failed condition

Intended Outcome

When there is any test failed, return non-zero (1 would be good enugh)

How will it work?

In the command piperider run, call exit(1) if there is any test failed.
