test: avoid throttling

Enabling verbose logging showed that the initial cluster ready check
and pod logging were getting throttled by the default rate limiter in
the Kubernetes client. We probably don't want that and don't need to
worry about a runaway process or fairness, so we can avoid the
throttling and its associated log messages by setting a nop rate
limiter before creating the client.
