openstack-helm-infra/values_overrides/prometheus/nodes.yaml
Vladimir Kozhukalov 8b29037cec Move values overrides to a separate directory 
This is the action item to implement the spec:
doc/source/specs/2025.1/chart_versioning.rst

Also add overrides env variables

- OSH_VALUES_OVERRIDES_PATH
- OSH_INFRA_VALUES_OVERRIDES_PATH

This commit temporarily disables all jobs that involve scripts
in the OSH git repo because they need to be updated to work
with the new values_overrides structure in the OSH-infra repo.
Once this is merged I4974785c904cf7c8730279854e3ad9b6b7c35498
all these disabled test jobs must be enabled.
