Extract version upgrades into a dedicated script for instrumentor configure stage

In #20056 (closed) we shrunk down the ring0 pipeline to only run the configure stage.

That first iteration allowed us to validate that it was possible to run a single stage in absence of external changes (only the GitLab version can change).

The next step is to identify the bare minimum amount of operations we should perform to only upgrade GitLab.

We want to edit the Instrumentor image so that for the configure image it will add an additional script bin/deploy that will ignore all the terraform changes as well as limit the Ansible run to only the tag necessary to upgrade the whole installation.
