Backport
This PR is auto-generated from #19915 to be assessed for backporting due to the inclusion of the label backport/1.7.x.
The below text is copied from the body of the original PR.
The Nomad client expects certain cgroups paths to exist in order to manage tasks. These paths are created when the agent first starts, but if process fails the agent would just log the error and proceed with its initialization, despite not being able to run tasks.
This commit surfaces the errors back to the client initialization so the process can stop early and make clear to operators that something went wrong.
Closes #19847
