Re-create the CI cluster in staging
The current ci cluster in staging is on the wrong PostgreSQL version (12.8) and the wrong ubuntu version (18.04).
Due to this wrong setup we are not able to execute the minor upgrade in the cascade cluster.
We need to fix this cluster to test the whole procedure.
Acceptance criteria:
-
Setup correctly the ci cluster, with the versions that we use in production
