Issue #4 #3 Add node reference variable to module configuration

Purpose

Our exercise has us building a controller that loads an administrator-controlled node when a certain path is used. We want the administrator to be able to select a node to be rendered on the path /thunderdome using twig.

Approach

1. Create a module settings page that lists configuration variables for your module
2. Create a new configuration variable called something like important_node
3. Add an input to the module configuration page. Use an entity_reference field type to select a node on the configuration page.
4. Use the new controller to pull in the new configuration variable and then load the node and then render it using a render array

How to

1. As an administrator, navigate to the module settings page and select a node.
2. As a user (anonymous or admin), navigate to /thunderdome and see the node get rendered.
