Since addition of platformstack dependency, kitchen converges fail

Now that this depends on platformstack, it needs .kitchen.yml work to disable the 'service[chef-client]' resource, or it won't converge. We need to move this to chef-zero, add additional chef-solo guards like platformstack has, or use attributes to disable parts of platformstack that don't work with this kitchen, such as `node['platformstack']['omnibus_updater']['enabled']`.

I'm seeing that particular toggle not being set causing:
```
            Chef::Exceptions::ResourceNotFound
           ----------------------------------
           Cannot find a resource matching service[chef-client] (did you define it first?)
```
