Moved loadService into endpoints.js

Moved loadService into endpoints.js

This is an interm branch before moving all of the load
service code into the db. It's sole purpose is to ensure
that we could remove loadService from the app and move
it to it's next logical spot. The next quick follow up
branch will be to move all of the service loading code
into the db.

Tests which directly test the code in app have been removed
but the endpoint tests indirectly test the code and should
be fine until it is moved into db and real tests made right
away.

Please take a look.

LGTM

Question about the plan in the MP though, when you say DB you mean db.service
(ServiceList), or do I misunderstand?

LGTM - nice work Jeff cleaning up these service-related activities.  As you
mentioned on IRC this code won't stay long in endpoints.js which is a relief.
