Check sysinfo for Cpuset cpu.shares and blkio

Browse source 
Carried: #14015

If kernel is compiled with CONFIG_FAIR_GROUP_SCHED disabled cpu.shares
doesn't exist.
If kernel is compiled with CONFIG_CFQ_GROUP_IOSCHED disabled blkio.weight
doesn't exist.
If kernel is compiled with CONFIG_CPUSETS disabled cpuset won't be
supported.

We need to handle these conditions by checking sysinfo and verifying them.
