Chart changes to support k8s v1.16

This PS includes changes to support k8s 1.16, these
changes would work with existing kubernetes version
as well. A seperate change would be done to uplift
kubernetes to 1.16.

Hyperkube short aliases are removed in k8s 1.15
https://github.com/kubernetes/kubernetes/pull/76953

- Rename binaries of kubernetes components in promenade and
corresponding anchor helm charts
- Kubelet flag --allow-priveleged is deprecated in k8s 1.15 and
removed in 1.16. Remove the flag from kubelet template. This
fix will be backward compatible as long as psp are defined.
