Description

We need to implement the `usage` method in the `network/cni` isolator to expose metrics relating to a containers network traffic.

On receiving a request for getting `usage` for a a given container the `network/cni` isolator could use NETLINK system calls to query the kernel for interface and routing statistics for a given container's network namespace.
