SFDC Cases Counter:

MCO shouldn't honor the request to apply cgroups v1 on 4.19 cluster.

Remove the Cgroupsv1 references from the MCO code and the UTs, e2e tests

Should we remove the CgroupV1 references or reject the request and update the nodes.config object's status that the "Support to configure CgroupModeV1 is deprecated"?
If the CgroupModeV1 is to be removed, should we deprecate the CgroupMode field from the nodes.config spec?
