Bootstraps' pivot service races with bootkube

This is a clone of issue OCPBUGS-3164. The following is the description of the original issue:
—
During first bootstrap boot we need crio and kubelet on the disk, so we start release-image-pivot systemd task. However, its not blocking bootkube, so these two run in parallel.

release-image-pivot restarts the node to apply new OS image, which may leave bootkube in an inconsistent state. This task should run before bootkube
