optimize CI tests

[tarakby]

When retrying tests, the setup phases are also retried which slows downs the overall jobs. Setup includes installing tools and building relic lib. This PR separates the setup phase from running the actual tests. The setup steps won't be retried if the tests fail.

Test jobs updated:

• unit-test
• unit-test-modules
