ID-807 stubbing out Routes for new ToS routes

[gpolumbo-broad]

Ticket: https://broadworkbench.atlassian.net/browse/ID-807 (and other tickets that need new ToS routes

What:

Stubbed Akka Routes all returning 501 just to get them in place so we don't end up stepping on each other as we implement the new routes.

Why:

Because akka routing is gross, and scalafmt makes it even worse, and I really really don't want to have to do manual code merges in a yucky file.

How:

<For your reviewers' sake, please describe in ~1 paragraph how this PR accomplishes its goal.>

<If the PR is big, please indicate where a reviewer should start reading it (i.e. which file or function).>
