Replace kube-master with kube_control_plane (#7256) 
This replaces kube-master with kube_control_plane because of [1]:

  The Kubernetes project is moving away from wording that is
  considered offensive. A new working group WG Naming was created
  to track this work, and the word "master" was declared as offensive.
  A proposal was formalized for replacing the word "master" with
  "control plane". This means it should be removed from source code,
  documentation, and user-facing configuration from Kubernetes and
  its sub-projects.

NOTE: The reason why this changes it to kube_control_plane not
      kube-control-plane is for valid group names on ansible.

Installation Guide

Ambassador

The Ambassador API Gateway provides all the functionality of a traditional ingress controller (e.g., path-based routing) while exposing many additional capabilities such as authentication, URL rewriting, CORS, rate limiting, and automatic metrics collection.

Ambassador Operator

This addon deploys the Ambassador Operator, which in turn will install Ambassador in a kubespray cluster.

The Ambassador Operator is a Kubernetes Operator that controls Ambassador's complete lifecycle in your cluster, automating many of the repeatable tasks you would otherwise have to perform yourself. Once installed, the Operator will complete installations and seamlessly upgrade to new versions of Ambassador as they become available.

Configuration

  • ingress_ambassador_namespace (default ambassador): namespace for installing Ambassador.
  • ingress_ambassador_update_window (default 0 0 * * SUN): crontab-like expression for specifying when the Operator should try to update the Ambassador API Gateway.
  • ingress_ambassador_version (defaulkt: *): SemVer rule for versions allowed for installation/updates.

Ingress annotations

The Ambassador API Gateway will automatically load balance Ingress resources that include the annotation kubernetes.io/ingress.class=ambassador. All the other resources will be just ignored.
