sm service and sm-api service CPUShares are reduced to 512 out of 1024
since they exhibit severe CPU hog behaviour for extended periods
particularly during host configuration.
NOTE: CPUQuota may not be used for these services because they require
more than number of Platform CPUs during host configuration.
This is part of an overall set of adjustments are required for systemd
cgroups CPUShares, CPUQuota, and AllowedCPUs for key system services.
This will improve latency of Kubernetes critical components, and
throttles lesser important services.
