AC-7791 Build class library that will create cgroups for job tasks
 and assign memory, cpusets, devices and other resources to the task

This checkin takes care of memory and cpuacct cgroups. cpusets can
be easily completed but another sub-task will be created for cpusets
and enabling cpusets to be taken care of in cgroups will be done
in addition to just making a job part of the cpuset cgroup.
