you have 2 options.
either you can upload only the public key to nova api,
it does not need to create the private and public key you can just import an existing public key.
Your second option is to not use the api to inject the public key and instead use user_data.
Effectively you could embed the public key in the cloud-init userdata and install it your self via user_data
and cloud init.
