4c50b33ed5 Validate --cpuset-cpus, --cpuset-mems 
Before this patch libcontainer badly errored out with `invalid
argument` or `numerical result out of range` while trying to write
to cpuset.cpus or cpuset.mems with an invalid value provided.
This patch adds validation to --cpuset-cpus and --cpuset-mems flag along with
validation based on system's available cpus/mems before starting a container.

3ed5407e61 Check sysinfo for Cpuset cpu.shares and blkio 
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.

8539f493fa Add the memory swappiness tuning option to docker. 
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).
