Action 'delete' is already defined on `DropletKit::CDNResource`

Hi! Any call to droplet_kit api gives me this error:
```
ArgumentError: Action 'delete' is already defined on `DropletKit::CDNResource`

```

I've commented out this exception in resource_kit/method_factory.rb like this:
```ruby
module ResourceKit
class MethodFactory
def self.construct(object, resource_collection, invoker = ActionInvoker)
resource_collection.each do |action|
if object.method_defined?(action.name)
# raise ArgumentError, "Action '#{action.name}' is already defined on `#{object}`"
next
end
```

And it works fine. Exception raised for delete action for each resource.

Start at resource_kit/method_factory.rb and the CDNResource definition in droplet_kit/resources/cdn_resource.rb, then trace loading through droplet_kit/client.rb. Reproduce the resource-loading failure and compare it with the reported workaround. Done means DropletKit resources load and API calls no longer raise the duplicate delete-action error.
