[pdm-devel] [PATCH datacenter-manager] api: fail with HTTP 403 Forbidden if user does have access to resource

[Lukas Wagner]

As discussed in another patch series [1], if a user does not have
enough permissions to see a resource, we should fail with 403 Forbidden
instead of 401 Unauthorized. The UI relies on returning the correct
error codes, since a 401 will redirect the user to the login mask.

Notes:
    There are a few instances where we return 401 in auth/tfa related code
    which I didn't touch - not sure if any of these should also be replaced.
