Sebastiaan van Stijn 213a1891c7 Update TOC and change "overview" to "index"

This changes the index page URL for cluster to `/cluster/`
instead of `/cluster/overview/`, which makes URL navigation
more fitting the expectations.

Note that there's still issues to resolve; because we're adding links
to the *same* "reference" pages and "environment variables" in multiple
locations in the navigation tree, the navigation marks all occurrences
as "active". Which means that browsing the Docker CLI reference, and
going to the "cluster" section, will make the navigation jump to the
"Deploy Docker Enterprise" section.

Introduction and Overview of Docker Cluster	documentation, docs, docker, cluster, infrastructure, automation	Overview of Docker Cluster

Docker Cluster is a tool for lifecycle management of Docker clusters. With Cluster, you use a YAML file to configure your provider's resources. Then, with a single command, you provision and install all the resources from your configuration.

Using Docker Cluster is a three-step process:

Ensure you have the credentials necessary to provision a cluster.
Define the resources that make up your cluster in cluster.yml
Run docker cluster create to have Cluster provision resources and install Docker Enterprise on the resources.

A cluster.yml file resembles the following example:

{% raw %}

variable:
  region: us-east-2
  ucp_password:
    type: prompt

provider:
  aws:
    region: ${region}

cluster:
  engine:
    version: "ee-stable-18.09.5"
  ucp:
    version: "docker/ucp:3.1.6"
    username: "admin"
    password: ${ucp_password}

resource:
  aws_instance:
    managers:
       quantity: 1

{% endraw %}

For more information about Cluster files, refer to the Cluster file reference.

Docker Cluster has commands for managing the whole lifecycle of your cluster:

Create and destroy clusters
Scale up or Scale down clusters
Upgrade clusters
View the status of clusters
Backup and Restore clusters
