Jamie Lennox 179ed18c30 Don't create empty quota set requests
The way that getattr is called with the None default you will always
create a compute_kwargs dictionary with key: None values. This means
that we will always send these empty requests to the servers.

Change so that only actually changed values end up in the quota set
requests and get sent.
