- 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`

OS_PROJECT_ID is obsolete in keystone v3 and jinja expression
doesn't set openstack_tenant_id as expected because of
undefined env var. Fixed the expression.

This fixes #3014

The number of pods on a given node is determined by the  --max-pods=k
directive. When the address space is exhausted, no more pods can be
scheduled even if from the --max-pods-perspective, the node still has
capacity.

The special case that a pod is scheduled and uses the node IP in the
host network namespace is too "soft" to derive a guarantee.

Comparing kubelet_max_pods with kube_network_node_prefix when given
allows to assert that pod limits match the CIDR address space.

* Move front-proxy-client certs back to kube mount

We want the same CA for all k8s certs

* Refactor vault to use a third party module

The module adds idempotency and reduces some of the repetitive
logic in the vault role

Requires ansible-modules-hashivault on ansible node and hvac
on the vault hosts themselves

Add upgrade test scenario
Remove bootstrap-os tags from tasks

* fix upgrade issues

* improve unseal logic

* sysctl file should be in defaults so that it can be overriden

* Change sysctl_file_path to be consistent with roles/kubernetes/preinstall/defaults/main.yml

Changed from OS_PROJECT_ID to OS_PROJECT_NAME.

Changed from OS_PROJECT_ID to OS_PROJECT_NAME.

* allow installs to not have hostname overriden with fqdn from inventory
* calico-config no longer requires local as and will default to global
* when cloudprovider is not defined, use the inventory_hostname for cni-calico
* allow reset to not restart network (buggy nodes die with this cmd)
* default kube_override_hostname to inventory_hostname instead of ansible_hostname

Support ipvs mode for kube-proxy

Fix 'no such host' problem reported by commands *kubectl logs* and *kubectl exec*
when cloud_provider is OpenStack

Closes: #2147
