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.

Memory swappiness option takes 0-100, and helps to tune swappiness
behavior per container.
For example, When a lower value of swappiness is chosen
the container will see minimum major faults. When no value is
specified for memory-swappiness in docker UI, it is inherited from
parent cgroup. (generally 60 unless it is changed).

Now that docker sets /proc/sys/net/ipv4/ip_forward by default (unless
the user manually specifies "-ip-forward=false"), there's no need to
warn if its disabled.
