Fix local-volume-provisioner configmap template

fix registry_storage_class equals empty string

Use --bind-address instead of --address

Add image builder to create Docker vm's for kube-virt

Update kubectl and etcd download urls for mult-arch

Looks like the template is removing the trailing space between storage
class entries, and since CI only has one storage class we never hit this
issue. This change will prevent the yaml from printing on a single line
when multiple storage classes are defined.

Use Pypy portable on coreos

Upgrade kubernetes to v1.13.2

--address deprecated

Fix readOnly flag in kubeadm-config.v1beta1.yaml.j2

In v1beta1 of `ClusterConfiguration` the extraVolumes `writable` field was changed to `readOnly` and its boolean value must be negated.

Also, the json field for `useHyperKubeImage` was incorrectly capitalized.

Bugfixes for Local Volume Provisioner

Merge pull request #3996 from Bobonium/issue_3586_kube_router_with_external_loadbalancer_not_working

use api server loadbalancer ip if external loadbalancer is used (fixes kube-router deployment)

Added optional basic auth parameters

- Fixed an issue where storage class host directories were looped
through excessive target hosts
- Fixes examples in the LVP `README.md` to use nested dicts instead of a
list of dicts

* Makes local volume provisioner more dynamic

* Correct variable name in local storage provisioner defaults

* Updates external-provisioner readme

* Updates variable naming to be more clear, more documentation, fixes sample inventory

* Variable refactor, untangled some jinja2 loops

* Corrects variable name

* No variable substitution in dict keys, replaced with anchor

* Fixes default storage_classes dict, inline docs

* Fixes spelling in inline docs

* Addresses comments in review

* Updates all the defaults

* Fix failing CI task

* Fixes external provisioner daemonset

--limit doesn't work when using remove-node.yml as there is group listing with "hosts: kube-master" in the playbook. Thus, remove-node/pre-remove/post-remove tasks are skipped as they are filtered by group "hosts: kube-master"

* allows to override the bind addresses for controller-manager and scheduler

Useful for Prometheus metrics monitoring

* Add bind addr override support in kubeadm/v1beta1

Adds support for override of bind addresses for controller-manager
and scheduler in kubeadm/v1beta1

* Move location of bind address vars

* Remove double declaration of schedulerExtraArgs

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

fix ingress nodeSelector label

* remove os_family variable from bootstrap-os

* quote the conditions another time to fix the syntax error

* Use master node taint same as kubeadm configuration v1alpha3 or before.

* Fix mixup http/https in bootstrap-debian.yml

* Update bootstrap-debian.yml

The change implemented in #3908 remove line breaks for supplementary
addresses in kubeadm SANs, causing errors in the config file and
failure to bring cluster up. This commit reimplement line breaks in
between supplementary addresses.

- 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`
