The use of containerd and CNI functions has been refactored to reuse the same codebase. Added all network functionality to own directory and package. Removed netlink and weave library in favor of using CNI plugin result files. Rename containers handler to functions to clear-up functionality. Signed-off-by: Carlos de Paula <me@carlosedp.com>

// Package netlink provides a simple library for netlink. Netlink is
|
|
// the interface a user-space program in linux uses to communicate with
|
|
// the kernel. It can be used to add and remove interfaces, set up ip
|
|
// addresses and routes, and confiugre ipsec. Netlink communication
|
|
// requires elevated privileges, so in most cases this code needs to
|
|
// be run as root. The low level primitives for netlink are contained
|
|
// in the nl subpackage. This package attempts to provide a high-level
|
|
// interface that is loosly modeled on the iproute2 cli.
