In order to mitigate sporadic data races in etcd (publish error: etcdserver: request timed out"): - Add etcd_start_delay and kubelet_start_delay (defaults to a 5 sec.) - Increase default start sleep times to foo_start_delay from a 1 sec. - Add restart sleeping as well. - Add missing start sleep commands as appropriate.
