Based on the CephFS Provisioner Addon, the following changes have been made:
 - Upstream v2.1.1-k8s1.11
 - Configurable Provisioner replicas

* Fix the file path for all.yml and k8s-cluster.yml

* Fix --node-labels namespace error "unknown labels specified"

* Update templates and configs kubelet node-labels

* Lint everything in the repository with yamllint

* yamllint fixes: syntax fixes only

* yamllint fixes: move comments to play names

* yamllint fixes: indent comments in .gitlab-ci.yml file

* feat(external-provisioner/local-path-provisioner): adds support for local path provisioner

Helpful for local development but also in production workloads (once the
permission model is worked out) where you have redundancy built into the
software uses the PVCs (e.g. database cluster with synchronous
replication)

* feat(local-path-provisioner): adds debug flag, image tag group var

* fix(local-path-provisioner): moves image repo/tag to download role

* test(gce_centos7-flannel): enables local-path-provisioner in test case

* fix(addons): add image repo/tag to commented default values

* fix(local-path-provisioner): typo in jinja template for local path provisioner

* style(local-path-provisioner): debug flag condition re-formatted

* fix(local-path-provisioner): adds missing default value for debug flag

* fix(local-path-provisioner): syntax fix for debug if condition end

* fix(local-path-provisioner): jinja template syntax: if condition white space

- 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

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

Introduced variable `ingress_nginx_tolerations` to set custom
tolerations for Ingress nginx daemonset, to be able to schedule
ingress-nginx on dedicated nodes with taints.

* Support Metrics Server as addon (#3560).

* Update metrics server v0.3.1.

* Add metrics server test.

* Replace metrics server manifests with kubernetes/cluster/addons's.

* Modify metrics server manifests for kubespray.

* Follow PR#3558 node label node-role.kubernetes.io/master change

* Fix metrics server parameters base_metrics_server_... to metrics_server_...

* Fix too hard corded metrics_server_memory_per_node

* Add configurable insecure tls for metrics-apiservice

* Downloadable addon-resizer and extract parameter as variables

* Remove metrics server version from deployment name

* Metrics Server work when all masters has node role

* Download metrics-server and add-resizer container only on master

* ServiceAccount and ConfigMap is separated and fix application name

* Remove old metrics server clusterrole template

* Fix addon-resizer image specify

* Make InternalIP default for metrics_server_kubelet_preferred_address_types

Make InternalIP default because multiple preferrred address types does not work.

kubeadm sets node label node-role.kubernetes.io/master=''
and this is not configurable. We should use it everywhere.

- Local Volume StorageClass configuration is now manged by `local_volume_provisioner_storage_classes`, a list of maps that specifies local storage classes with `name` `host_dir` and `mount_dir` keys per entry
- Tasks and templates updated to loop through local volume storage classes
- Previous defaults for path/class names were not changed
- Fixed an issue where a `kubernetes/preinstall` was creating directories inconsistently with the `kubernetes-apps/external_provisioner/local_volume_provisioner` task
