autoscaler: update cloud-config-controller (#1268)

* autoscaler: update cloud-config-controller

modifies the behavior of the autoscaler to terminate worker and
controller nodes no longer needed when minSize is set manually.

Note that I had to delete the initial autoscaler pod after
deploying a new cluster with this modification in place.
After that initial autoscaler pod was deleted the second
pod functioned without errors and as expected.
I will update the issue comments with more details.

Fixes #1253

* update CA in cloud-config-controller with dnsPolicy: Default
