at /etc/kubernetes from the luks volume. Symlink must be present
only on the controller node only.

encryption-provider.yaml file based on the personality.
Test Plan:
PASSED: build-pkgs -c -p luks-fs-mgr
PASSED: bootstrap
PASSED: symlinks are created at /etc/kubernetes/ for
controllers only and not for compute/storage
