Increase cache size for leases

Browse Source 
The default size (100) is not enough for large clusters and results in
unnecessary restarts of kube-controller-manager watcher for leases, see http://perf-dash.k8s.io/#/?jobname=gce-5000Nodes&metriccategoryname=APIServer&metricname=LoadRequestCount&Resource=leases&Scope=cluster&Subresource=&Verb=LIST

This PR will make it match what we have for nodes.
