cv-c3c: add --image flag to deployment restart command

Browse Source 
Allows callers to override container images during restart, e.g.:
  laconic-so deployment restart --image backend=ghcr.io/org/app:sha123

The override is applied to the k8s Deployment spec before
create-or-patch. Docker/compose deployers accept the parameter
but ignore it.
