When a deployment is created and not all inputs are provided, we show:
Unable to create deployment. Not all required inputs have been specified...
... nice formatted list of all available inputs ...
400: Required inputs ['floating_network_name'] were not specified - expected inputs: [a python-style list of all available inputs]
We don't need the "400" at the beginning, and we don't need the "expected inputs" part because the list is already provided.
