closes CNVS-19046
Marketing is moving to take over the FFT form, which means
the user creation will occur via API, but they'll still need
to get the self-registration style emails to get passwords right
and such.
This provides a parameter to do so. It also pulls out a handful
of lines from the users_controller all related to how and which
notifications get sent, and moves them into a policy object, which
has some predicate methods for the controller to make decisions off
of, and also does the notification dispatching.
