In order to test eviction related functionality it will be convenient to have reasonable eviction defaults. At this moment exactly same flags are used by GCE environment kubelet will have a following flag: --eviction-hard=memory.available<100Mi,nodefs.available<10% Change-Id: I56ca03bc3c5467c8450150e292f7a346fa7772a9
