[hibernate-dev] Upgrades for ci.hibernate.org

[Gunnar Morling]

Hi Sanne,

Apparently you changed some of the OGM jobs to not use their own private
Maven repo any longer. What was the reason for that? I had chosen to work
with private repos intentionally, so to avoid interferences between
different jobs.

It may not be strictly needed as long as we don't run jobs in parallel on
one node, but I still prefer the original style because it removes one
level of complexity when it e.g. comes to the analysis of build failures.
