Subject: [PATCH] Allow configuring additional annotations on the generated
 workload

Add a spec.annotations (map[string]string) field. The operator renders
its entries into the generated workload's commonAnnotations, so users can
attach arbitrary annotations to the workload metadata. The field is empty
by default, so existing deployments are unaffected.
