Add `internal` attribute to routes

This is meant to provide a way for Action Cable, Sprockets, and possibly
other Rack applications to mark themselves as internal, and to exclude
themselves from the routing inspector, and thus `rails routes` / `rake
routes`.

I think this is the only way to have mounted Rack apps be marked as
internal, within AD/Journey. Another option would be to create an array
of regexes for internal apps, and then to iterate over that everytime a
request comes through. Also, I only had the first `add_route` method set
`internal`'s default to false, to avoid littering it all over the
codebase.
