Warnings about CORS in latest release

[Jay Pipes]

When running functional tests in Nova there are now a whole slew of warnings from the latest oslo_middleware release that look like this:

Captured stderr:
~~~~~~~~~~~~~~~~
    /home/jaypipes/src/git.openstack.org/openstack/nova/.tox/functional/local/lib/python2.7/site-packages/oslo_middleware/cors.py:137: DeprecationWarning: Method 'instancemethod.set_latent()' has moved to 'instancemethod.set_defaults()': CORS.set_latent has been deprecated in favor of oslo_middleware.cors.set_defaults
      allow_methods=sanitize(self.conf.get('latent_allow_methods'))

Would be great to have those cleaned up...

We can remove method set_latent in oslo.middleware once we confirm 'latent_allow_headers', 'latent_expose_headers'and 'latent_allow_methods' are not used in consuming projects. see

    def __init__(self, application, *args, **kwargs):
        super(CORS, self).__init__(application, *args, **kwargs)
        # Begin constructing our configuration hash.
        self.allowed_origins = {}
        self._init_conf()

        def sanitize(csv_list):
            try:
                return [str.strip(x) for x in csv_list.split(',')]
            except Exception:
                return None

        self.set_latent(
            allow_headers=sanitize(self.conf.get('latent_allow_headers')),
            expose_headers=sanitize(self.conf.get('latent_expose_headers')),
            allow_methods=sanitize(self.conf.get('latent_allow_methods'))
        )

    Remove method set_latent

    Method set_latent is deprecated in favor of method set_defaults in
    e9c3a23e845d8c53b266a3b2e4ca7fb0a5a0425a, we don't use this method
    in any project, it's safe to remove it now.
