[PATCH 2/6] Clean up Gitlab yaml

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

Factor out the registry into a common location.  Drop the worflow name, as all
it does is hide the commit message of the change that triggered the pipeline.
List all the stages.  Set a default expiry of 1 month.

Note all the current jobs as legacy.  Their naming scheme needs changing, and
we'll use this opportunity to switch formats too.  However, the artefacts need
to stay using the old name until the final staging-* branch using them is
phased out.
