Provide k8s 1.8 backwards compatibility for init-container secret copying, solves #1208
As discussed in #1208 (closed) this MR provides backwards (pre kubernetes 1.8.8/1.10) compatible copying of secrets from init-containers to the actual containers of sidekiq, unicorn et al. I smoke tested the change on minikube with kubernetes 1.13 and it didn't break anything.
