refactor vault role (#2733)
* 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

* specify ca and fix etcd check

* Fix initialization check

bump machine size

45eac53ec7 roles: kubernetes: preinstall: Install openssl-1.1.0 on Tumbleweed
The openssl package on Tumbleweed is actually a virtual package covering
openssl-1.0.0 and openssl-1.1.0 implementations. It defaults to 1.1.0 so
when trying to install it and openssl-1.0.0 is installed, zypper fails
with conflicts. As such, lets explicitly pull the package that we need
which also updates the virtual one.

Rename default_resolver to cloud_resolver (#2209)
Cloud resolvers are mandatory for hosts on GCE and OpenStack
clouds. The 8.8.8.8 alternative resolver was dropped because
there is already a default nameserver. The new var name
reflects the purpose better.

Also restart apiserver when modifying dns settings.

e5d353d0a7 contiv network support (#1914)
* Add Contiv support

Contiv is a network plugin for Kubernetes and Docker. It supports
vlan/vxlan/BGP/Cisco ACI technologies. It support firewall policies,
multiple networks and bridging pods onto physical networks.

* Update contiv version to 1.1.4

Update contiv version to 1.1.4 and added SVC_SUBNET in contiv-config.

* Load openvswitch module to workaround on CentOS7.4

* Set contiv cni version to 0.1.0

Correct contiv CNI version to 0.1.0.

* Use kube_apiserver_endpoint for K8S_API_SERVER

Use kube_apiserver_endpoint as K8S_API_SERVER to make contiv talks
to a available endpoint no matter if there's a loadbalancer or not.

* Make contiv use its own etcd

Before this commit, contiv is using a etcd proxy mode to k8s etcd,
this work fine when the etcd hosts are co-located with contiv etcd
proxy, however the k8s peering certs are only in etcd group, as a
result the etcd-proxy is not able to peering with the k8s etcd on
etcd group, plus the netplugin is always trying to find the etcd
endpoint on localhost, this will cause problem for all netplugins
not runnign on etcd group nodes.
This commit make contiv uses its own etcd, separate from k8s one.
on kube-master nodes (where net-master runs), it will run as leader
mode and on all rest nodes it will run as proxy mode.

* Use cp instead of rsync to copy cni binaries

Since rsync has been removed from hyperkube, this commit changes it
to use cp instead.

* Make contiv-etcd able to run on master nodes

* Add rbac_enabled flag for contiv pods

* Add contiv into CNI network plugin lists

* migrate contiv test to tests/files

Signed-off-by: Cristian Staretu <cristian.staretu@gmail.com>

* Add required rules for contiv netplugin

* Better handling json return of fwdMode

* Make contiv etcd port configurable

* Use default var instead of templating

* roles/download/defaults/main.yml: use contiv 1.1.7

Defaults for apiserver_loadbalancer_domain_name (#1993)
* Defaults for apiserver_loadbalancer_domain_name

When loadbalancer_apiserver is defined, use the
apiserver_loadbalancer_domain_name with a given default value.

Fix unconsistencies for checking if apiserver_loadbalancer_domain_name
is defined AND using it with a default value provided at once.

* Define defaults for LB modes in common defaults

Adjust the defaults for apiserver_loadbalancer_domain_name and
loadbalancer_apiserver_localhost to come from a single source, which is
kubespray-defaults. Removes some confusion and simplefies the code.

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

0c7e1889e4 Support for disabling apiserver insecure port
This allows `kube_apiserver_insecure_port` to be set to 0 (disabled). It's working, but so far I have had to:

1. Make the `uri` module "Wait for apiserver up" checks use `kube_apiserver_port` (HTTPS)
2. Add apiserver client cert/key to the "Wait for apiserver up" checks
3. Update apiserver liveness probe to use HTTPS ports
4. Set `kube_api_anonymous_auth` to true to allow liveness probe to hit apiserver's /healthz over HTTPS (livenessProbes can't use client cert/key unfortunately)
5. RBAC has to be enabled. Anonymous requests are in the `system:unauthenticated` group which is granted access to /healthz by one of RBAC's default ClusterRoleBindings. An equivalent ABAC rule could allow this as well.

Changes 1 and 2 should work for everyone, but 3, 4, and 5 require new coupling of currently independent configuration settings. So I also added a new settings check.

Options:

1. The problem goes away if you have both anonymous-auth and RBAC enabled. This is how kubeadm does it. This may be the best way to go since RBAC is already on by default but anonymous auth is not.
2. Include conditional templates to set a different liveness probe for possible combinations of `kube_apiserver_insecure_port = 0`, RBAC, and `kube_api_anonymous_auth` (won't be possible to cover every case without a guaranteed authorizer for the secure port)
3. Use basic auth headers for the liveness probe (I really don't like this, it adds a new dependency on basic auth which I'd also like to leave independently configurable, and it requires encoded passwords in the apiserver manifest)

Option 1 seems like the clear winner to me, but is there a reason we wouldn't want anonymous-auth on by default? The apiserver binary defaults anonymous-auth to true, but kubespray's default was false.
