    Added Keystone and RequestID headers to CORS middleware

    This patch makes use of oslo.config's genconfig hooks to add
    nova-specific default config values to the generated configuration.
    It also adds this same method to nova's configuration parsing logic,
    to ensure that these default values are also the ones used at runtime.
