kubelet config: --protect-kernel-defaults

[jackfrancis]

We want to deliver the --protect-kernel-defaults kubelet option, but are currently unable because we're building clusters without the expected kernel default settings. On a recently built 1.7 cluster:

kubelet.go:1323] Failed to start ContainerManager [Invalid kernel flag: vm/overcommit_memory, expected value: 1, actual value: 0, Invalid kernel flag: kernel/panic, expected value: 10, actual value: 0, Invalid kernel flag: kernel/panic_on_oops, expected value: 1, actual value: 0]
