Separate arguments and tests based on: require the personal credentials or not.

[a-t-0]

Determine whether there exists a solution for the personal creds requirement above the repository for testing purposes.
Perhaps move the check for personal cred presence from import.sh to prerequisites.sh.

And separate the tests based on:

• whether they need personal creds or not
• Whether they need the GitLab server to be running on the parent device or not.
• Whether they need the GitLab server to be running in the docker parent device or not.
• Whether they need the GitLab runner to be running on the parent device or not.
• Whether they need the GitLab runner to be running in the docker parent device or not.
• Whether they break the GitLab server installation or not.
• Whether they break the GitLab runner installation or not.

Then allocate the tests for GitLab CI accordingly.
