auth/config.go

Test our GetClientHandler function, add isAuthError helper. Add a helper that identifies whether the error passed to it is an authentication error or is some other type of error. This is useful fo checking whether or not an internal error occurred while authenticating users. Update all instances where we call our authentication helper to make them use the new error helper. All tests continue to pass. Add a new test case for retrieving a client as an unauthenticated user. This clears the client's secret from the response before sending it. Update the GetClientHandler function to return the secret when the owner of the client used Basic Auth in the request. Add a new test case for retrieving a client as an authenticated user, both the owner and a non-owner user. This makes sure the secret is divulged only in the appropriate cases.
