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).

9e02a83937 remove ip_forward warning 
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.
