Netchecker is rewritten in Go lang with some new args instead of
env variables. Also netchecker-server no longer requires kubectl
container. Updating playbooks accordingly.
Change version for calico images to v1.0.0. Also bump versions for
CNI and policy controller.
Also removing images repo and tag duplication from netchecker role
