c0221c2e72 Add --dns-loop-detect to dnsmasq used in kube-dns
It prevents DNS loops when host's DNS server is a localhost DNS server,
or when DNS server of cluster is also added as an upstream DNS server

e3dcd96301 kubedns & kubedns-autoscaler: Stick to master nodes. (#2909)
* kubedns & kubedns-autoscaler: Stick to master nodes.

 - Tolerate only master nodes and not any NoSchedule taint
 - Pods are on different nodes
 - Pods are required to be on a master node.

* kubedns: use soft nodeAffinity.

Prefer to be on a master node, don't require.

* coredns: Stick to (different) master nodes.

     - Pods are on different nodes
     - Pods are preferred to be on a master node.

0c6f172e75 Kubernetes Dashboard v1.7.1 Refactor
This version required changing the previous access model for dashboard completely but it's a change for the better. Docs were updated.

* New login/auth options that use apiserver auth proxying by default
* Requires RBAC in `authorization_modes`
* Only serves over https
* No longer available at https://first_master:6443/ui until apiserver is updated with the https proxy URL:
* Can access from https://first_master:6443/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/#!/login you will be prompted for credentials
* Or you can run 'kubectl proxy' from your local machine to access dashboard in your browser from: http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/
* It is recommended to access dashboard from behind a gateway that enforces an authentication token, details and other access options here: https://github.com/kubernetes/dashboard/wiki/Accessing-Dashboard---1.7.X-and-above

45044c2d75 Reschedule netchecker-server in case of HW failure.
Pod opbject is not reschedulable by kubernetes. It means that if node
with netchecker-server goes down, netchecker-server won't be scheduled
somewhere. This commit changes the type of netchecker-server to
Deployment, so netchecker-server will be scheduled on other nodes in
case of failures.

1cfe0beac0 Set ClusterFirstWithHostNet for Pods with hostnetwork: true
In kubernetes 1.6 ClusterFirstWithHostNet was added as an option. In
accordance to it kubelet will generate resolv.conf based on own
resolv.conf. However, this doesn't create 'options', thus the proper
solution requires some investigation.

This patch sets the same resolv.conf for kubelet as host

3a39904011 Move calico-policy-controller into separate role
By default Calico CNI does not create any network access policies
or profiles if 'policy' is enabled in CNI config. And without any
policies/profiles network access to/from PODs is blocked.

K8s related policies are created by calico-policy-controller in
such case. So we need to start it as soon as possible, before any
real workloads.

This patch also fixes kube-api port in calico-policy-controller
yaml template.

Closes #1132
