Set leader-elect=false for scheduler and controller manager

both the scheduler and controller manager constantly ping the apiserver to ensure leader election. From the docs:

```
Enable this when running replicated components for high availability.
```

which we don't really need in minikube. This should reduce overall overhead by ~12%
