If Kubernetes > 1.6 register standalone master nodes w/ a
node-role.kubernetes.io/master=:NoSchedule taint to allow
for more flexible scheduling rather than just marking unschedulable.

Prior this would fail because we didnt set max ttl for vault temp

* Bump tag for upgrade CI, fix netchecker upgrade

netchecker-server was changed from pod to deployment, so
we need an upgrade hook for it.

CI now uses v2.1.1 as a basis for upgrade.

* Fix upgrades for certs from non-rbac to rbac

This aligns calico component versions with Calico release 2.1.5 and
fixes an issue with nodes being unable to schedule existing workloads
as per [#349](https://github.com/projectcalico/cni-plugin/issues/349)

Signed-off-by: Bogdan Dobrelya <bogdando@mail.ru>

This does not address per-node certs and scheduler/proxy/controller-manager
component certs which are now required. This should be handled in a
follow-up patch.
