[api spec] Update authN and authZ errors
Associate HTTP 401s with Authentication errors rather than Authorization errors. Changes the meaning of the UNAUTHORIZED error to be authentication specific. Defines DENIED error code to be associated with authorization errors which result in HTTP 403 responses. Add 'No Such Repository' errors to more endpoints.
