How about naming this auto_signin_snackbar.h or
auto_signin_snackbar_controller.h? That seems sufficiently descriptive without
being a mouthful.

auto_signin_snackbar_controller.h is nice because it has the same name as the
Java class, so it's easy for developers to figure out which cc files goes with
the java file and vice versa.
