Qiang Huang 12a63757db rename Set to Apply 
The name `Set` would be used to do dymanic changes of resource configs
in the future. For now, `Apply` also makes more sense.

Victor Marmol 2636848328 Remove sampling from libcontainer CPU stats. 
Sampling should be done by higher layer in configurable intervals. This
change removes the percentage stat as sampling is required for this.

Nicholas Weaver 8597998244 Fixes logic for calculating percentage for cgroups.Stats.CpuStats.CpuUsage.PercentUsage 
Previous logic divided a uint64 by a uint64 losing precision before multiplying by clock ticks and cpus
This fix maintains precision before converting back to uint64

Vishnu Kannan a4b8bef91b Added a new method cgroups.GetStats() which will return a cgroups.Stats object which will contain all the available cgroup Stats. 
Remove old Stats interface in libcontainers cgroups package.
Changed Stats to use unit64 instead of int64 to prevent integer overflow issues.
Updated unit tests.
