Add the GitLabSoS class that restructures some calls.

I understand that at a first look this single commit might seem a bit much. My thoughts are that we try to split up as much as possible in functions, this should make it easier to implement features such as --logs-only and -d /tmp/report-1234/

Before completely rewriting the script into a Class I like to hear what you think.

The diff is hard to read (and I hate that) so if you like the idea but not this MR. I can split this MR into smaller bits making the diffs clearer.
