Schedstat - fix affinity values and default
SYSCPUS is actually set as default but refers to 0-0. This should be fixed the following way:
- Change default value to dynamic 0-max_cpus or 1-max_cpus
- use value setaffinity to allow also _unspecified, i.e. max allocation
- if unspecified, orchestrator and system have all to use the same cpu's.. i.e. no affinity settings for cgroups
- test unspecified value
