Related to the availability of shared runners, for merge_requests/post_merge
builds only, the PSI/OpenShift infra may actually help in order to achieve
more stable execution times due to the usage of private runners.
As explained by Dan, that will not help for the merge request builds,
because those are executed in the context of the submitter's fork and
as such don't have access to any runners we might deploy ourselves.
It would help speed up the post merge phase, but once we move to a
merge request workflow we'll want to test as much as possible at the
time the merge request is submitted, and there won't be much that
needs to happen after the changes hit master... So dedicated runners
might actually not be useful outside of supporting non-Linux targets.
