8080 is a pretty common port, using nodelocaldns_ip:8080 still
prevents node processes or hostNetwork=true processes to bind to *:8080
so switch to 9254 by default (prometheus port is 9253)

Based on the CephFS Provisioner Addon, the following changes have been made:

 - Configurable Provisioner replicas

This reverts commit 31650862.

* Use Kubernetes 1.14 and experimental control plane support

* bump to v1.14.0

* Enable nodelocaldns by default

* Enable nodelocaldns by default

* nodelocaldns is now default

* Disable enable_nodelocaldns for the addons CI jobs

Disable enable_nodelocaldns for the addons CI jobs to make sure things still work without nodelocaldns

* Vagrantfile: Bump openSUSE to Leap 15.0

* roles: container-engine: Add 'containerd' package for openSUSE

The 'containerd' package contains the docker-containerd and
docker-containerd-shim binaries. We also need to ensure that the latest
version is installed since an older version may already be present (eg GCE
images)

* Remove docker log-opts for opensuse

* roles: bootstrap-os: Use lowercase 'o' for openSUSE

OpenSUSE is not a valid family name. The correct one is openSUSE

* roles: bootstrap-os: Update zypper cache before first installation

The zypper cache may be outdated so ensure that it's fully updated
before we try and install the bootstrap packages.

* enable kubelet client certificate rotation

* change to variable kubelet_rotate_certificates

Both kubedns and dnsmasq modes are long not maintained.
We should run dns_late steps at the end because sshd
makes DNS lookups during Ansible run and has 2s timeouts
for each failed lookup trying to connect to coredns before
it is ready.

values from inventory in roles/kubespray-defaults/defaults/main.yml
hardcoded values in roles/container-engine/defaults/main.yml

dns_servers set empty in roles/container-engine/defaults/main.yml and skydns_server not set in docker_dns_servers variables
also set default value for manual_dns_serve

another variables in roles/container-engine/defaults not need to set

Looks like `epel_enabled` was not configured for the epel install in `bootstrap-centos.yml`. Also, there were no conditionals that would trigger bootstrap for RHEL.

use api server loadbalancer ip if external loadbalancer is used - this fixes the broken kube-router deployment

- Creates and defaults an ansible variable for every configuration option in the `kubeproxy.config.k8s.io/v1alpha1` type spec
  - Fixes vars that were orphaned by removing non-kubeadm
  - Fixes previously harcoded kubeadm values
- Introduces a `main` directory for role default files per component (requires ansible 2.6.0+)
  - Split out just `kube-proxy.yml` in this first effort
- Removes the kube-proxy server field patch task

We should continue to pull out other components from `main.yml` into their own defaults files as I did here for `defaults/main/kube-proxy.yml`. I hope for and will need others to join me in this refactoring across the project until each component config template has a matching role defaults file, with shared defaults in `kubespray-defaults` or `downloads`
