Description of problem:

Customer used Agent-based installer to install 4.13.8 on they CID env, but during install process, the bootstrap machine had oom issue, check sosreport find the init container had oom issue

NOTE: Issue is not see when testing with 4.13.6, per the customer

initContainers:

• name: machine-config-controller
  image: .Images.MachineConfigOperator
  command: ["/usr/bin/machine-config-controller"]
  args:
• "bootstrap"
• "--manifest-dir=/etc/mcc/bootstrap"
• "--dest-dir=/etc/mcs/bootstrap"
• "--pull-secret=/etc/mcc/bootstrap/machineconfigcontroller-pull-secret"
• "--payload-version=.ReleaseVersion"
  resources:
  limits:
  memory: 50Mi

we found the sosreport dmesg and crio logs had oom kill machine-config-controller container issue, the issue was cause by cgroup kill, so looks like the limit 50M is too small

The customer used a physical machine that had 100GB of memory

the customer had some network config in asstant install yaml file, maybe the issue is them had some nic config?
