Inclusion of a project_id in API URLs is now optional, and no longer
required. Removing the project_id requirement facilitates supporting
Secure RBAC's notion of system scope, in which an API method is not
associated with a specific project.
The API v3 routing is enhanced to provide duplicate routes for API
methods that traditionally required a project_id in the URL:
- The existing route for which a project_id is in the URL
- A new route for when the URL does not include a project_id
To test both routes and ensure there are no regresssions, the "API
samples" functional tests include a project_id in the URLs, and the
rest of the functional tests do not include the project_id. This is
handled by changing the 'noauth' WSGI middleware to no longer add the
project_id, and adding a new 'noauth_include_project_id' middleware
filter that implements the legacy behavior.
A new microversion V3.67 is introduced, but it only serves to inform
clients whether the project_id is optional or required. When an API
node supports mv 3.67, the project_id is optional in all API requests,
even when the request specifies a earlier microversion. See the spec
Ia44f199243be8f862520d7923007e7182b32f67d for more details on this
behavior.
Note: Much of the groundwork for this is based on manila's patch
I5127e150e8a71e621890f30dba6720b3932cf583.
