Review request for mesos, Jie Yu and Qian Zhang.


Fixed code style.

Bugs: MESOS-5647

Repository: mesos


On receiving a request for getting `usage` for a given container
the `network/cni` isolator uses getifaddrs(3) glibc function. The
function returns basic networking metrics for each networking
interface in the container networking namespace. It should work
right out of the box on all modern Linux-based systems.

To get more networking metrics please use Netlink Protocol Library.
However, you will have to open NETLINK sockets in each networking
namespace and manage them from the `network/cni` isolator.
