On _ssh-init.sh.tpl, despite one change the runAsUser for the
nova-compute container on the securityContext, the ssh keys are always
being copied into the 'nova' user's folder. This change fixes it by
getting the correct user defined on the securityContext and copying the
keys to its correct folder.
