Title: Defines runner methods for ChefSpec matchers

This enables us to target these resources by using ```chef_run.docker_image('resource-name')```.

Example:

```ruby
it 'notifies the database container to redeploy' do
image = chef_run.docker_image('database')
expect(image).to notify('docker_container[database]').to(:redeploy).immediately
end
```
