Please include --rs parameter and Environment Variable for registry secret name

[rmey]

I would add something like this:
export REGISTRY_SECRET=myicrsecret
and in run scripts:
ibmcloud ce app create -n helloworld --rs $REGISTRY_SECRET --image ${REPOSITORY}/helloworld

@rmey sorry for the delay - I didn't notice your issue until just now. I'll look into this. One of the issues with adding cool options like this is that it might appear to complicate things for newbies.... so it's balancing act between "keep it as simple as possible" and "flexibility". But it's a good idea...
