[Keep] Keep uses appropriate HTTP status codes for failed DELETE requests
|Velocity based estimate||0 days|
When a DELETE request fails because a call to the API server could not be executed successfully, the HTTP status returned by the API server should be passed through to Keep's DELETE response:
- Respond 403 Forbidden if the token is valid (users.get responds 200) but does not pass is_admin/scopes verification, or users.get responds 403 (which is another scope problem).
- Respond 401 Unauthorized If the token is invalid (users.get responds 401) (This probably means the token has expired.)
- define an ArvadosApiError type that includes the API server HTTP status code
- change sdk.ArvadosClient.CallRaw to return an HTTP status instead of an error message
