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>
