train-stable-7 misses the hostname command
https://cern.service-now.com/service-portal?id=ticket&table=incident&n=INC3834666
We are missing the hostname command in registry.cern.ch/kubernetes/heat-container-agent:train-stable-7 we need to build a new image or stop relying on the hostname command to address #51
train-stable-7 was introduced here https://gitlab.cern.ch/kubernetes/automation/releases/kops-openstack/-/commit/16efb0767585fc7da596b5c8f427a4ab0f378d2e#4c52de710ca63f8e421beb30f9831599c772115c_452_450 but I can not track where it was built.
This issue breaks creation of cluster/nodegroups with baremetal nodes.
