$envvar replacement not fully supported

[purplecabbage]

It looks like the env var replacement of manifest.yml keys is not fully supported.

This example from the openwhisk docs does not seem to work.

actions:
      hello_world_env_var_parms:
        function: src/hello.js
        inputs:
          name: $FIRSTNAME
          place: ${TOWN}, ${COUNTRY}

FIRSTNAME is replaced, but TOWN and COUNTRY are not.
