commit 8b4b3abdaf8d9392bd3a3b53813e5ed4eeed53b6

    Moved CORS middleware configuration into oslo-config-generator
    
    The default values needed for sahara's implementation of cors
    middleware have been moved from paste.ini into the configuration
    hooks provided by oslo.config. Furthermore, these values have been
    added to the default initialization procedure. This ensures
    that if a value remains unset in the configuration file, it will
    fallback to using sane defaults. It also ensures that an operator
    modifying the configuration will be presented with that same
    set of defaults.

Bug description:
  It was pointed out in http://lists.openstack.org/pipermail/openstack-
  dev/2016-February/086746.html that configuration options included in
  paste.ini are less than optimal, because they impose an upgrade burden
  on both operators and engineers. The following discussion expanded to
  all projects (not just those using paste), and the following
  conclusion was reached:

  A) All generated configuration files should contain any headers which the API needs to operate. This is currently supported in oslo.config's generate-config script, as of 3.7.0
  B) These same configuration headers should be set as defaults for the given API, using cfg.set_defaults. This permits an operator to simply activate a domain, and not have to worry about tweaking additional settings.
  C) All hardcoded headers should be detached from the CORS middleware.
  D) Configuration and activation of CORS should be consistent across all projects.

  It was also agreed that this is a blocking bug for mitaka. A reference
  patch has already been approved for keystone, available here:
