CI pipeline for mysql unit tests

Summary

The pipeline should also run the tests with a MySQL as backend server. This MR implements this.

See also #33 (closed).

Focus

• Does the MySQL pipeline fail at the expected point?
• Is outsourcing pipeline code to a Makefile a reasonable step to prevent redundancy in the scripts?

Test Environment

Just watch the pipeline run.
