SLI is used for cgroup performance monitoring, but it is not
necessary for some cases(such as running the linux without
cgroups on the embedded device). Therefor we add this
configuration to decide whether package SLI into kernel or not.

currently, /proc/stat displays cpu usage for real cpu,
add support to display cpu usage based on cpuacct,
online file on cgroupfs is changed to display cpu count
minimum of cpuset and cpuacct. sysctl
cgroupfs_stat_show_cpuacct_info is used to start this feature.

Sli max latency is lightweight latency monitor metrics, the monitor
tool could get the data with a little overhead. And the accuracy of
the metrics is controlled by the sampling frequency of the monitor
tool. When the performance jitter was occurred in the system, we can
get some help from these lateny metris.
