Export repository scope helper functions

Browse Source 
`docker.Authorizer` requires library clients to configure scope via context.
It is helpful for the clients to use the helper (currently private) functions
for generating scope string and to use that function with the combination of
other scope-related ones (e.g. `docker.WithScope`).
