Extract version upgrades into a dedicated script for instrumentor configure stage
In #20056 (closed) we shrieked down the ring0 pipeline to only run the configure
stage.
That first itereration 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.
