We no longer restart the Members service based on the Stripe service
being updated, which meant that if it was initially configured with
missing URL's and later Stripe connected, it would not get the new
config until a server restart. This moves the last of Stripe config into
the Stripe service, so that all things concerning Stripe can be handled
in one place and updated together.

This module is going to encapsulate all of the Stripe related logic, so
I'm renaming this file to be a little more specific about what it
relates to. Essentially this module will export a Stripe Service, and
this file is just one part of that.
