Allow to test upgrade from 1.1.1 in MR pipelines via ci-feature::test-upgrade-from-1.1.1

What does this MR do and why?

Introduce a new technical label ci-feature::test-upgrade-from-1.1.1 that change the default behavior of our pipelines. When this label is set the pipelines will test an upgrade from 1.1.1 version to the dev branch

Note that activating this feature will increase the pipelines duration (similar to ci-featuretest-rolling-upgrade as it will probably trigger a rolling upgrade).

The upgrade will use as a target the current dev branch (which can differ than main + dev branch commit, if the branch is not rebased)

This MR allow to have this feature quickly available until the rework of the deployment-test is done
