This commit will have protokube eagerly retry to connect to kube-apiserver instead of the 1 minute sync loop.
Another benefit is that we know that tasks are run in order and that labels are always applied before channels etc
Previously as an optimization we would start the kubelet from
protokube, after we had mounted the disks. This helped avoid e.g. the
apiserver going into backoff waiting for etcd.
However, this no longer achieves anything with etcd-manager - nothing
happens on this front until after we start the kubelet anyway.
Doing this both takes protokube out of the dependency sequence here
(slightly faster boot time), but also removes the systemd dependency
from the protokube image. (So we can get a smaller image, perhaps
even distroless)

We still don't actually support sensitive options, but it doesn't look
like we need them, MountSensitive is just called with empty
sensitiveOptions in a few places.
