The MembersAPI using the OfferRepository coupled it to the internals of
the Offers Module - instead we pass the "external" API - so that we can
change the internals, and not have to update the MembersAPI's usage.
no-issue
Because we only called `init` if the labs flag is enabled, when starting
up a site without the flag enabled - the listener for adding redirects
wasn't active. So new Offers would not have their redirects setup.

This updates the Members & Offers modules to provide support for using
Offers in Stripe Checkout.
Members module now needs a handle to the Offers module repository, and
as such we have had to reorder the services boot order.

This adds the Offers service which will allow us to build out an Admin
API to communicate with it. As well as wiring up the redirects to the
site app.
