Description

This is a utility for MESOS-38 https://issues.apache.org/jira/browse/MESOS-38

Create a collection of utilities to read information from the proc filesystem. This will be used in MESOS-38 to collect most of the information for the process-based isolation usage reporting mechanism. These utilities will also be used for certain functionality in monitoring lxc-based isolation because not all of the information needed is available via the cgroup interface, such as the start time of the container.
