Update kube-dns version to 1.14.2
https://github.com/kubernetes/kubernetes/pull/45684

Make etcd_backup_prefix configurable. Ensures that backups can be stored on a different location other than ${HOST}/var/backups, say an EBS volume on AWS.

In the etcd container, the etcd data directory is always /var/lib/etcd. Reverting to this value, since `etcd_data_dir` on the host maps to `/var/lib/etcd` in the container.
