Environment variables passed via -e flag not applied on deploy

[lkingland]

Environment variables passed with func deploy -e KEY=VALUE are not
included in the deployed service spec. They work correctly with
func run -e, but on deploy the env vars are missing from the
container spec.

Expected: -e MYVAR=value on deploy sets the env var in the Knative
service container spec, the same way it does for local runs.
