Manila APIs have had the requirement to include
project_id in the URLs since the very beginning.
This comes from an old assumption that our APIs
would be differentiated per-tenant on the cloud,
and we would allow different kinds of API endpoints
(public, admin, internal, etc). While it is possible
to set up different endpoints against the API
service, the same and complete API is exposed at
each of these endpoints.
We don't _need_ the project_id information that
we receive in the URL for any of our APIs to
function. We rather authorize tenants by gathering
information from the Identity service (Keystone)
and wrapping that into a RequestContext object
that we then rely on to ensure namespace isolation.
Removing the requirement for "project_id" simplifies
our API endpoint structure in the service catalog
as well as provides a way for system scoped users
to interact with manila without having to declare
their project.
In order to make project_id optional in urls, the
possible values of project_id have to be constrained.
This change introduces a new configuration option
so deployers may control that. This configuration
option defaults to accepting UUIDs with and without
dashes.
Since manila can be used in standalone deployments
without the need for Keystone, this change introduces
a noauth middleware that can work without project_id
in the URL paths.
The API version has been incremented to signal this
change to end users. When 2.60 is available, deployments
may drop "project_id" in the service catalog endpoint
for Manila and end users applications can stop needing
it as well (if they don't already rely on the service
catalog for this data).
