Bump QPS on namespace controller

Browse Source 
https://github.com/kubernetes/kubernetes/pull/62913 switched from using a client pool, where each groupVersionResource got its own rest client, to a single client.

This increases the QPS to account for increased requests using a single rest client rate limiter.
