Update the k8s.AsFunctionStatus so that it populates the env variables

Steps to Reproduce (for bugs)

1. Follow the testing instructions from feat: Add missing fields to the describe output faas-cli#915

Context

While working on openfaas/faas-cli#913 I was adding the list of secrets to the describe output and I noticed several fields were missing, including the env variables. These are on the FunctionStatus type returned by the info endpoint, but when I patched the CLI in openfaas/faas-cli#915, the env variables were always empty.
