Could not create the Namespace in Kubernetes - config:push

I'm using deis config:push to send the environment variables from a .env file to my application and it's giving me

```Creating config... ...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...o...oError: Unknown Error (400): {"detail":"Could not create the Namespace in Kubernetes"}```

How is that that I cannot create a namespace?

Start by reproducing the `deis config:push` entry point with an application and `.env` file, then trace the Kubernetes namespace creation request that produces the 400 error. Done means identifying the cause and making the command create the config successfully instead of reporting that the namespace could not be created.
